Yeah, that seems like an overly complicated description.

Well, as I understand it, you have menus, which are utilities, and
then you have items, which are adapters between the object
IBrowserRequest and the menu. You can also have submenuitems, which
are "pointers" to a new menu.

And you have a metho on the menu utilities that says "get the menu for
this object".

So, it should be quite straightforward, really. a grok.Menu, a
grok.MenuItem and a grok.SubMenuItem, all of which more or less only
need to subclass the zope3 objects that are already there. And a
grokker tyo register them automatically.

Or am I missing some complexity?
