If this mode is only for showing the menu, then at least the mode's
name should reflect that.

And once again: I don't think I see the justification to have a minor
mode whose only job is to show a menu-bar menu.  I'm not even sure why
we need to have a project-mode at all: AFAIU the project.el features
are always available, so no mode is needed.
