The thing is I don't think I can guarantee that it will be rarely.
Since Gtk is new and some issues not really solved (tooltips in
menus, Gtk toolbar), I expect more Lisp_Objects may be needed in
Gtk callback data.  I would prefer to be able to make local changes
in a Gtk only file rather that propagate these changes into files
that really have nothing to do with GUI toolkits.

Also, I think minimizing the number of files that have to have
tests for USE_GTK is a good thing.
