Emacs doesn't have a Customize UI to alter keymaps, so changing defvars
to defcustom isn't currently useful (because there's no :type that
could be used other than `sexp').

It would be possible to create such an UI, of course, but it would work
quite differently than all other Customize widgets.  I don't think
anybody wants to have the entire definitions of keymaps in their .emacs
files -- they want to add a keystroke or remove a keystroke or two, and
that's it.  (And, besides, they want to get new keystrokes that are
added to the maps.)

But it'd be nice to have; sure.
