I didn't look at your WP_Dependency stuff at first because of comments  
from others that it wasn't the right way to do it.  I just looked at  
your PHP code and am confused by it as it seems you've got some  
generic code in there and also some plugin specific stuff for Contact  
Form 7?  Why the hardcoded info in something you wanted to integrate  
into core?  If it was an example it should have been external to your  
WP_Dependency code.

Ignoring my confusion it looks like WP_Dependency requires defining  
dependency relationships for plugin versions rather than defining  
explicitly named interfaces and determining dependencies based on  
those interfaces.  While in some cases the former may still be  
necessary I think we'd be adding to the problem by making things more  
fragile going the route of WP_Dependency.

JMTCW anyway.
