I'm not sure I understand what advantage your proposal gives over the  
current mechanism for doing this.

That is, add to your __init__.py file:

from pkgutil import extend_path
__path__ = extend_path(__path__, __name__)

Can you describe the intended advantages over the status-quo a bit  
more clearly?
