This would be nice. But it isn't.

The addMenuItem directiv has dependency to the menu directive
if you use a own Adding view.

That's the only reason where we see right now. 

The alphabtice order of configure.zcml like Stephan proposed
is one solution. But I like a more explicit solution for this
like Dominik proposed with a additional application level
for 3rd party packages.
