Yeah, if there was one place I'd expect to be free from photographers passing judgement on the equipment choices of others, it's here.
Many of us are using garden-variety hardware from the 1970's (or older), and in many cases it wasn't even designed for 44x33. If we were all after maximum image quality, we'd all be asking for 100% crops from Otus and Coastal Optics and such instead of posting low-res snaps from Canon and Pentax.
Let's make this thread about adapting lenses to GFX, and we can go to the "Everyone else bought the wrong camera" thread to have that discussion.
Took a coworker's Pentax 645 25/4 (the digital version with the deeper hood) on a Fotodiox Pro adapter with manual aperture control for a spin. Optically, it's excellent, though you do need to stop it down a bit before the edges catch up with the central resolution, and it has a drop-in filter holder for 40.5 filters. It shipped with a clear filter and circ pol when new, and the drawer has a control wheel for the circ pol. My coworker was also able to get a NiSi variable ND filter to work with the wheel as well.
Overall, it wasn't worth the bulk or the fussiness of adapting. The only advantages it offers over the Fuji 23 are a slightly better MF experience and less vignetting wide open.

This is the first report I've seen about one of these on a GFX camera. I've always been curious.
The Leica PC Super-Angulon R 28mm f/2.8 by Schneider-Kreuznach has come up from time-to-time in this thread.
It's been on my "maybe" list for a couple years now. After going through the 28mm large image circle alternatives (PC-Nikkor 28mm shift and Pentax K 28mm shift), I finally bought one of the Schneider/Leica lenses and adapted it to my setup.
I'm very pleasantly surprised by how good the lens is. I had modest expectations based on other peoples' experiences on GFX cameras. It's much better than I thought it would be. I like it a lot.
It's a shift-only lens in its native mount. I use it as a tilt-shift lens on my outfit. This required ripping it apart and remounting it.

I left a comment regarding the Leica R 28mm f2.8 Super Angulon PC in your thread on dpreview regarding modification of the Cambo Actus lens plate due to difficulties in mounting/removing the lens from the lens plate.
Also, I anticipate receiving the Laowa 20mm f4 Shift lens in Canon EF mount to be delivered from Adorama on hopefully Thursday or Friday.

But they never built a 28 f/2.8 mirrorless lens and they have built the 110 f/2.5 APO Macro for mirrorless.
OK, maybe they didnt. I honestly havent paid too much attention to all but their SLR and Leica M offers.
But I'm not sure why you think thats relevant. I dont think they introduce new (old) SLR lenses so people can adapt them to mirrorless ? I think they introduce new SLR lenses because they think theres still sufficient demand for them that they can make a profit from introducing these lenses.
Canon EF might be dead, but I heard Nikon still makes twice the sales with DSLR gear than with mirrorless.

It was my last stop before giving in and buying the Fuji 23. Optically, I could've been very happy with it, but it's a lot of lens to put on the end of a 43mm tube. If there were a tilt/shift adapter that allowed for aperture control and could reasonably stand up to over a kilo on the lens mount side, it would probably be worth seeking out the D-FA version that has a large enough IC to cover the full 645 frame. Alternately, I guess you could tape the aperture arms to a constant f/8ish, where the lens is at its absolute best, and use it on the existing tilt/shift adapters, but I'd still be worried about hanging that much weight off them.

I actually think when they made the recent SLR lenses for Nikon they were either thinking that Nikon users were going to be slow to switch to mirrorless or they would adapt these lenses to mirrorless. And neither of these things was unreasonable to think at the time they made those lenses. Now that it is pretty clear that CV is making mirrorless lenses for Nikon, I think it is pretty clear that both the original reasons for making F mount lenses probably no longer hold. If one of those holds, however, it is that people are willing to adapt as lots of people have moved from Nikon DSLR to Nikon mirrorless, so if CV is going to make any F mount lenses then it makes sense they will be making lenses that they expect people to adapt to mirrorless so they won't be making F mount lenses when they could easily make Z mount lenses instead. That reasoning, IMO, is why the mirrorless lenses CV makes is relevant to what lenses they are likely to make for Nikon cameras.
Nikon 58/1.4G @ about f./1.8 with Steelsring Nik-F/GFX adapter on the GFX 100s. This is uncropped and with no lens profile applied."Just" color graded in Adobe ACR CC (latest version).
There's obviously something wrong when the corner is sharper than the border and the center on the GF 63. I think it's misfocused. Never seen such soft results from my 63.
A quick little in studio test of the close focusing abilities of the Contax 350mm f/4, which focuses to just under 6 ft. While you would generally use this lens for further distances, I had a moment while documenting this sax and tried this lens out at somewhere in the six to seven foot range. What I found is that wide open it sucked, while shooting at closer to infinity it was fine wide open or a stop down. Stopping down to f/11, while not in the same league as the Contax 120mm macro, it's really not bad at all. The lens is a freaking beast, but it is a long, fairly fast lens designed for medium format.
