The implementation done in af4150f and 1ccac46 is a good implementation in the sense that it solves the problem, but it raises some issues:
In my opinion, we should revert this to the previous implementation, with a "dummy" content type, that it will be picked up by Plone's getMenuItems.
However, the best solution(in my opinion) would be if Plone's getMenuItems implemented some kind of adapter lookup that will allow any package to extend the functionality of this menu.
