Even if that is the case it is not helpful here.  The best command to use for
this is the _only_ command that exists (so far): `mouse-major-mode-menu'.

Consider this user's request:
http://lists.gnu.org/archive/html/help-gnu-emacs/2010-12/msg02016.html
My suggestion to him was this:

>> If you don't care about modes that might bind `C-mouse-3'
>> specially, then just remap its command:
>>
>> (define-key global-map [remap mouse-save-then-kill]
>>             'mouse-major-mode-menu)

Unless there is a _command_ that does what `mouse-major-mode-menu' does, you
cannot do something like that.  Or you need to roll your own command.

Emacs should offer a command for this, as it has in the past.  What is wrong
with the existing `mouse-major-mode-menu' that it should be removed?  If you
have in mind a better definition, then please add it.  But Emacs should have a
command for this, whatever the name and whatever the exact definition.
