Of course it does: if you use `defkeymap', changing the definition of the
defkeymap macro is all that's needed to take advantage of ":type 'keymap"
when it finally appears.  With the usual `defvar', it requires changing each
and every `defvar'.  And if it later turns out that a (defcustom foo
... :type 'keymap) is not enough, you'll have to go through every keymap
definition all over again.

You seem to consider the cost of introducing a macro `defkeymap' to be
enormous (large enough that it needs very significant benefits to justify
itself).  The macro would probably be about 20 lines long and phasing in its
use is easy, so I see the cost as being negligible.
