You don't know if you don't try.  Why not pose the
question in emacs-devel?

> So, barring that, 

Why bar it, without trying?  Just posing the question
should immediately let you know whether there is lots
of opposition (in emacs-devel, at least).  If there
isn't, that's not proof that there won't be opposition
in the wider world, of course.  But if there's lots of
opposition at least you'll feel better about binding
it to `C-h x'.  If posed, the alternative should be
mentioned, including the binding of new key `C-h x'.

IMO, this should be combined with the other changes
I mentioned in emacs-devel:

1. Add `describe-option', and bind it to, e.g., `C-h o'.
2. Change `describe-function' and `describe-variable',
   so that, with a prefix arg, they do `describe-command'
   and `describe-option'.

(In terms of doc, #2 lessens the need to advertise
those new commands.)
