Respectfully disagree. I do appreciate your writeup, though.
Human hands didn't get smaller with the removal of the mirror. So while it's absolutely easier to carry a body -- broken down without a lens on it -- it is less enjoyable, less comfortable, less real estate for controls and dedicated buttons when actually using it.
So shrinking down every FF body because everyone it doing it is the behavior of lemmings. It implies a lack of insight on Canon's part to see that folks are headed to Sony for a dozen reasons other than size.
If Canon will have 4 or 5 lines of RF mount bodies, they would be foolish to not consider the unique ergonomic needs of each target user base.
There is no one body footprint to unite them all, and Canon playing that there might be surely seems like a cost containment / shared inventory move. And I honestly hope I'm wrong about that.

I have had my hands, albeit that they are large Merkan hands...on mirrorless Fuji's, Oly's, Sony's, Canons and Ricohs. (Sadly not Leicas) While I love my 5D3 ergonomics, I can go smaller, I actually would like the R5 WITH an L bracket attached to be the same size as a naked 5D body (that means without bracket) However, I might be an atypical user since I use handstraps 99% of the time. Rounded corners are lovely for that style of a hold. Button placement is paramount if I am spending thousands of dollars, the R felt weird to me, all those other brands felt either misplaced or cramped when it came to buttons and ergonomics.
Not everyone in the larger ML camp wants it to mimic the 5D series in size, the 6D would be nice or something close. But whatever they do, joystick, af trackball, AF ON, D Pad etc etc, put them where it's intuitive! (Basically, near where the thumbs rest)
