After spending a bunch of time on PS "correcting" the RAW images, I end up with what the camera JPEG looked like had I shot in JPEG to begin with. Serious question: why waste time shooting in RAW when I'm going to spend hours in PS correcting lens flaws?
I haven't seen anyone serioiusly answering this part (unless I missed it).

Reality check --You missed it!
The first response that you missed was from NJPhotographer, p1 #14, 18 hours ago.
You've missed at last 4 additional responses informing you that Adobe products support a lens profile for the RF 16-28mm f2.8 IS STM.
You did seem to finally acknowledge that in an earlier post today:

Just to reiterate what I stated in post #17 on page 1 of this thread, ACR (and Lr) do support this lens. Support was introduced with v 17.2, which would have been April 2025. If you have not updated lately, that is likely the reason you don't have profiles for the lens.
I'll log in and check it again. Thanks!
But you haven't communicated to us that you've checked it yet, or the result.
It would be useful to us if you would provide the following:
1) the Release/version of PhotoShop you are using
2) the Release/version of ACR you are using
That might help us understand why you aren't getting the lens profile assistance (distortion, vignetting, diffraction corrections) that are causing you so much grief.
You made the same statement about the Tamron 11-28 RF in a different thread. I don't have the RF 16-28 so I haven't been able to respond to your not being able to get corrections for this particular lens, but I do have the Tamron 11-28.
-- The Tamron lens corrections have been applied to photos that I took in June 2025 and cataloged into Lightroom. I took those images 4 months earlier than the images you've posted to your "Tamron Lens ... Samples" folder, dated from Oct. 2025
-- While I don't have the RF 16-28, both Lightroom Develop module (i.e., the LR ACR frontend) and Photoshop ACR window show that the corrections for the RF 16-28 are available and can be applied even to my Tamron lens. The lens correction for that lens is clearly available in the current Adobe software releases.
