I do not know all the details of how Emacs keybinding works, but I had an
impression that something-x sequence is triggered if you type something-X
and you do not have an explicit binding for something-X but you do have a
binding for something-x.

IOW, if I only have

	(define-key global-map "\C-xc" 'compile)

then both "\C-xc" and "\C-xC" runs "compile", but in addition to the
above if I also have

	(define-key global-map "\C-xC" 'grep-find)

then I can invoke these two commands with lower- and upper- case 'c/C'
after control-x.

If people have been relying on the historical behaviour that typing "R"
marked the path resolved (which may internally have been implemented with
whatever way), and if you are removing that binding, wouldn't that now
expose them to whatever happens to be bound to "r"?

And worse, it is bound to git-remove-file.  Shouldn't you at least rebind
the "R" to something safer, like beep?

Am I grossly misunderstanding how Emacs keybindings work?  Is the
experiment I did in the initial part of the message with the global-map
relying on some "magic" that only appears in global-map, and there is no
problem doing this in the map this patch is about?
