Agreed.  FWIW, this is another part of the subview package.  I tried  
to spell this out very explicitly.  If contentproviders agreed on the  
subview interfaces, or something like them, then we would have a  
lower level agreement for all of the page component technologies out  
there.

The zope.widget package in the branch is currently in disrepair, but  
the intent is for widgets to be subviews.  The subview package  
actually grew out of the widget work.  This won't be ready for 3.2.

I personally don't think that I want default widget look-up to  
require (context, request, view), as opposed to the current (context,  
request), so I'd be in favor of widget interfaces extending the  
subview interfaces, not the contentprovider interface.  If for some  
reason someone wanted a widget system with lookups based on  
contentprovider then that could be an additional layer, still using  
all of the (context, request)-based code.
