Hmmmm.  Since I am aware of the API vs implementation conversations about the destiny/definition of openstack, I should point out that there is immense leverage and preference for a community supported standard implementation and code base.  In fact, in my commercial role, I insist that Openstack vendors commit back to the main code stream.  But the APIs openstack brings to market need to both enable consistent semantics (while overtime reducing the set of them) and competitive extension.

Full Stop.
