Yes, but most people don't change that. And certainly most new Emacs users
wouldn't want to change something they already are used to just to accomodate
to a "new" program they are trying out.

Yes, but how key-description describes it can change what keys users
actually press.
OK. I should have written "there is reason to think <M-tab> won't work".

It's not memorable for most new users. But maybe there is nothing
better left to use.
Then I think it would be good if key-description avoided description
that might lead
people to press combinations of keys that won't work at least. (Just
like it's good that
backward-kill-sexp is on ESC <C-delete>, ESC <C-backspace>
doesn't mention <C-M-delete> or <C-M-backspace>...

Sure, but I don't like that to be prerequisite knowledge for using Emacs.
