Yes, no doubt, but practical cost constraints were not my point. Rather, I was speaking to Canon's willingness to push its entries in the APS-C category into more premium territory, which would be necessary for it to create the camera that most of us would want. The cost of such a camera would of necessity be higher, and maybe higher than Canon's marketers would believe is sustainable.
I'd still be happy with what I wanted when the R7 came out: An R6 with an APS-C sensor. Swap out the R6's sensor for the most capable, best looking APS-C sensor that budget can produce. Keep everything else the same so moving between this and an R6/5 is nearly seamless. Keep the pixel count down enough to keep noise under control. Even a 24MP APS-C sensor gives more pixels per duck than an R5, but without spending $4k to crop out half the image.

That’s a fair point, and I do agree that it is hard for Canon to make and APS-C camera into a premium product… since their FF bodies already cover that.

If Canon is happy with offering the relatively low resolution R1 to its photojournalist clientele, it could make sense to aim a crop camera with 40 mp to its wildlife crowd. The former doesn’t need the resolution, while the latter needs resolution but mostly reach.

Not that different on 100MP MF sensors and that doesn't seem to stop them.
For personal anecdote... I've started experimenting with diffraction-limited shooting, basically f/16 and shallower on my 6D, to see what I can get out of it after processing.
Theoretically diffraction is just one of many bottlenecks to final output resolution - but you can shoot as narrow as you want so long as the output resolution satisfies your end product.

Maybe they are bringing back APS-H with a 40MP stacked sensor. That would be fine with me.
Make it square, and use it for the R3 II!
Would have the advantage of better IBIS (more room in the sensor box than full-frame), would crop out the weakest parts of full-frame lenses, and potentially would be very, very fast. Bigger battery would also be helpful for battery, and dare I say video.

The last thing that would stop me from buying any camera would be lack of a dedicated battery grip.
I think you left out a key part of my comment, which went:
I think the number one thing Canon must do with the R7 Mark II (after offering a dedicated battery grip for it, haha)...
This parenthetical was meant to be humorous, because certain people here on FM made such a big deal about this.
But in another way, the lack of a battery grip can be seen as an indicator of product positioning, and I think most of us would prefer that an R7 Mark II hew more closely to the 7D Mark II template.
I could agree with you, because I rarely purchase the battery grips for my own use. But I can't imagine how the camera would occupy that more premium niche without having at least an option for one. Battery grips have legitimate uses for advanced users (or just for people with larger hands).

I would never buy a battery grip either. In the old days it gave you more FPS or better AF or something, but now only battery life. Today we have USB-PD so there is less need for that either.

As far as any diffraction concerns, Jan Wegener (and a lot of other people) use 1.4 and 2x on 100-500, f/10 & f/14 max aperture. He probably used R5, still I doubt the diffraction equations like that very much. But it seems to do just fine.
So I'd be interested in 40mp aps. Yes they seem to make the lenses best a lot of the time at 5.6 lately but there's not any law of physics saying f/8+ can't be great, best performance, afaik

I mainly use mine when I expect to be taking a lot of portrait orientation shots. It's much more comfortable and stable.

Same. I'd rather just carry an extra battery or two to pop in — smaller and lighter solution.
As to the issue with shooting vertically, I don't even think twice about turning the camera 90 degrees to do that. It feels really natural to me.

YMMV.
Shooting with one hand on top is fine if you're going back and forth. But shooting a longer, heavier lens for extended periods is just a lot more comfortable with a grip.

Not for me. The left hand is always supporting the lens anyways.
Most grips don't have all the functionality of the body available at your fingertips in the vertical orientation

TCs suck more or less on the 100-500. The 1.4x sucks less, but it's still mostly an emergency measure when you are reach limited at 500mm. The 2x sucks more and is rather impractical. I've used about six 100-500s and a couple of RF 1.4x TCs with similar results. For whatever optical reason you should to stop down to f/11 with the 1.4x with the 100-500 at 500. The IQ is not primarily reduced by the f-stop due to diffraction, but the lens+TC.

That's interesting he seems to be doing quite well using it, i doubt it's competitive vs your 500 though at 100% im a direct comparison. Are you saying f/11 on the lens, or f/11 effective, 1/3 stop down or 1 1/3? They always used to say one stop down for 1.4 to get best performance after basically adding 7 elements to your lens, not too surprising imo
I have a hard time seeing advice using tc's on zooms, they used to say not to do that. Currently a thread about 70-200/2.8 having 2x recommendations though, I'd probably be pretty hesitant to do that
