Look at you complaining about eyelash focus. The real issue is the Fuji AF algorithm ignoring the person in front of you to go right to the random face in the back.

Best we can hope for is single shot eye-AF that doesn't focus on the eyelashes.
Threads about Fujifilm improving their AF are among the dumbest on the Internet and always end as a train wreck. No one is waiting around for Fujifilm's AF to get better. Folks have either adapted, accepted, or moved on.
Most everyone is looking forward to improved photo equipment here in the FM gear forums.
If Fuji AF is problem that is something that they should be working on.

It's not a 'pro lem' for 99.9% I've been using AF since e the beginning, and it's marvellous compared to that, it improves all the time. And for the vast majority of situations it's not even necessary, manual focus is fine. You have to rely on your own resources either way, it's YOUR job as photographer to get it sharp where you want it, using whatever aids you can work with.
Like any automation, it takes skill to use effectively, and when you come up against it's limitations, learn how to work it, or move on to a different tool that will help you solve your problem.
Or nowadays you can sit at your keyboard and whinge incessantly at every opportunity about your 'problems', real or imaginary. From experience or just hearsay.

Where do you get the 99.9% from? What I see on the fora is a much higher rate of folks not happy with Fuji's AF.
Well certainly on this forum, a high percentage of posts are by a few of you moaning on. But that doesn't amount to much compared to the legions of people who get on with producing excellent work with Fuji. And the percentage is situations.
There are a good number of members here who do know the issue and from time to time provide input. But there are a number of die hard deniers here who can't tolerate that there is an issue, too. And even more people on other sites. So, your 99.9% has no basis in reality, really.
For the avoidance of doubt, the situations where it falls short are most likely af-c tracking of fast moving items, probably 0,1% of the photos taken with Fuji cameras, and most seem happy with Xh2s performance, it is unrealistic to expect that level of performance in smaller, lighter and cheaper bodies.
The 'issues' you go on about seem to be focus beyond infinity, which I don't believe is an issue unless the focus locks there, which brings us to your second hobby horse, lack of locking focus on af-s, in I quote 'certain situations', which you see reluct to specify so we can see where the problem lies. I don't experience that issue, unless there are reasons, typically items in the focus box at more than one plane of possible focus. Sometimes the ca,era chooses the plane I don't want. That happens with my Nikons too, always has, and I don't considerit a 'fault' merely something to adaptmy technique to avoid. Last week I tried it out to see of I could reproduce your issue, 100-400 @ 400 so problems immediately obvious, fill the focus box with a flat brick wall opposite, locks focus every time out f about 20-30 tries, no problems. Focus distance indicator was absurdly inaccurate, reading about 7m instead of 30, but it was absolutely consistent.
There are two ther forums I know about, DP review which I haven't bothered with fot years as debate is generally un intelligent, and Fuji X, where I can't remember a single discussion asserting major AF issues.

"reluctant to specify" I have provided detailed description of both issues, the AF-S inconsistencies and the focus beyond infinity, and provide guidance how to test yourself. But it seems you rather don't.
I don't recall that, could you give me a link please?
Just do a search: Fuji AF-S issues
https://www.dpreview.com/forums/threads/fuji-inconsistent-autofocus-issue-pt-3.4714490/
And there is more: https://www.thewanderinglensman.com/2022/04/fujifilm-usersthere-is-issue-that.html
When I bought my Xpro2 one of the first lenses I got was the 14mm, and it is a favourite. I immediately noticed the erratic readings of the distance indicator. This puzzled me as it didn't corelate to actual results, where the focus plane was actually where I put it. So I did some tests, when used in af-s indeed the focus scale is totally unreliable and inconsistent, but the actual focus point seemed to be exactly where I put it, consistently, and use over 8 years has confirmed it. It seems better with longer focal lengths but as I discovered the other day at 400mm its consistent but inaccurate. Tests on manual focus with the 14 were more encouraging, and I often use the scale for manual hyperfocal point focus at f/8 for views, and with the 23mm too. If in doubt I also use Bbf as it's done at full aperture, and neither 14 nor 23 seem to have any focus shift.
In short, I suggest you have jumped to the wrong conclusion, it's the focus scale which is inaccurate (and could usefully be improved) not the actual AF.
There are other reasons why af-s might be inaccurate, the most frequent one is sloppy use, with items in the focus box at more than one distance, the camera cannot know your intentions as to which item you want sharp, it's more or less pot luck which is chosen, usually the most contrast. I am not suggesting uhou are guilty of that but it is a common error.

Perhaps two years ago when this same bugaboo ("focus beyond infinity") was the subject of one of the many other threads that have veered off track onto this subject, I did a series of tests with the 14mm lens and with the 27mm f/2.8 — after reading from the usual source that the "problem" afflicted wide angle lenses.
I could find no evidence of this problem at all. (I photographed several series of scenes multiple times looking for the infamous inconsistent focus, even picking scenes with potential problems such as the inclusion of subject at a range of distances that the camera might have a hard time picking from.
I went back and forth on this with that poster — yes, he's in this thread again, too — and finally just gave up interacting with him over this obsession. (It is a shame, since he is right about certain issue in other posts I've seen here, but this continuing obsession does not help his reputation, I'm afraid.)
To folks who think there's a problem: Fine. For the rest of is, don't you think that if there was some real-world, consistent, significant, and specific problem like this that it would have been picked up by all or most Fujifilm users by now?
