When will you know? I don't want to change this twice, so it would be
great to learn first, whether the protocol will turn out to be of any
use for you.
To be honest, I don't see any potential use for the protocol itself. We
need to have an abstraction for the menu representation, but this is
already there. Why would anybody use menu items that aren't of a
subclass of NSMenuItem?
