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

like Dominik proposed with a additional application level
for 3rd party packages.
