Yes, but if a keymap were a defcustom, then the whole keymap would be
in your .emacs, and you would not receive any updates if the keymap
definition changed, since that affects the *default* defcustom value.

Now if you wanted to define a defcustom type for changing bindings in an
existing keymap, thatʼs a different proposition (and we already have
define-key, so Iʼm not so sure of the utility).
