The Customize menus basically needs to load everything.  They have
been disabled for GNU Emacs for that reason, but was fully enabled for
XEmacs (with delayed generation) last time I checked (many years ago).

They are not really that practical though, the menu structure becomes
too deeply nested to be useful.
