Why?  Why should we not document both?

I am not, like you, claiming that my experience or preference
should be the only thing documented.  I'm for a big tent,
documenting what you prefer (M-) and what I prefer sometimes
(C-).  Not because you or I prefer this or that, but because
Emacs lets you use either one, and each is useful.

I've justified it.  And it's not bloat, but useful info for
users.
