Right, so you "need to adjust things".  This case really doesn't seem to
be any different.

No part of Emacs needs such a command, and very few users (or external
packages) would use it.  So I'm far from convinced it is warranted.

Exactly.  Something along lines of

  (defun my-command ()
    (x-popup-menu nil mouse-menu-major-mode-map))

should do the trick.

mouse-menu-major-mode-map works as well or better (better because C-h
k can be used to find the name of a function bound to a particular menu
entry) for all uses we care about.  So we don't need
mouse-major-mode-menu any more.
