I'm not sure I'd even call most of these suggestions but more-so workarounds. The OP was asking if others have had issues with face detect specifically. Most of his responses were having to defend 10 pages of accusations of trolling. OP said "face detect AF really draws me to the mirrorless options. I ordered a Z8 and after my first testing I'm finding the eye detect to be slightly off, often getting the end of the nose instead of the iris. and "My serious enquiry was is there a known focus issue with face tracker and is there a fix"
I don't think single point AF, 3D tracking, disabling face detect, etc are solutions for what the OP was asking about (face detect). It's clear that there is something more going on here than many are leading on. Why can't face/eye detect be relied upon for so many users?
A few users said they have no issues with face/eye tracking but most responses inferred there are indeed issues with eye-AF and suggested workarounds like:
"disable face detect", "the Nikon required using 3D AF mode and sometimes a custom small box as opposed to auto area",
"there are times when subject detect isn't doing exactly what I want it to do and that's when I turn it off and just use AF-C 3D tracking with the AF-ON button", "
"it takes a bit more time to figure out the best focusing modes on the Z8 vs Sony",
"Nikon AF is a complex and trickier beast than Sony",
"A peculiarity of Nikon focus is that it's much more difficult to get a Nikon camera to focus on a backlit subject",
"The first couple of days with my Z8 were frustrating because of the AF",
"The A7RV is more reliable to get iris focus almost all the of the time",
"First, the Z8 is not like the D850 with respect to autofocus. It’s more complex and flexible with respect to AF.","you need to understand what AF options to use and when",
"Using an F/4 or slower lens as it gets dark can yield inconsistent focusing in a way that my Canons/Sonys never did when the light dimmed.",
"Now, if you’re shooting a Plena at MFD, you’re only going to get an eyelash in focus anyways",
"This is further complicated by the fact that the camera will indicate that it has achieved focus in these conditions, but upon review it has not. It has in fact front or rear focused…",
"My Fn2 button is dedicated to the Single Point AF mentioned above that instantly achieves perfect focus 100% of the time.",
"Using my Z8 with the 85/1.2 and the plena in AF-C and subject detection on , I ALMOST NEVER HAVE PERFECT FOCUS ON THE EYE BALL : MOST ON THE EYE LASHES AND THE GLASS FRAME!",
"I had the Sony a7r v and now a Nikon z6iii. The Sony eye af looks a lot better to me for photos.",
"Frankly, there are probably better cameras than the Z8/9 if certain types of portraiture are a big part of your work",
"Where I think it falls apart is if there's a lot of action and if you crank up the ISO - I think Sony hangs in there longer on the eye af partly due to the AF motor of the lenses."

I did share some very clear, explicit and proven recommendations as to how the camera should be configured to maximize the effectiveness of eye focus. My results are outstanding, clearly superior to what I got with the best focusing Sony.
I am sorry, I don’t believe for a second that the OP had not already reached a conclusion when he posted his initial « question ».
Hs purchase of a Sony body before trying to make the Z8 works validates beyond any possible doubt the troll theory. Real people don’t do that. This is simply Sony promotion at work.
The very title of the post was designed to distill FUD even without reading the content of the discussion. This was not random.
Cheers,
Bernard
