There for awhile non apple menulets needed to be black and white only, only apple's could be color. And I think even now all non apple menulets have to be left of apple's. (and you can't move them as you can with apple's)

Still see stuff like this everyday in the console messages too:

See

MenuCracker is now loaded. Ready to accept new menu extras. Ignore the failure message that follows.
