OpenStack my drop Hyper-V support...

In a move to pressure a founding member to start pulling their weight the OpenStack team is considering pulling support for Microsoft's Hyper-V.  The developers are supposedly calling the Hyper-V code old and slow moving.  We saw the report from this article on computerworld.uk.  

Should they drop support?  Will this convince Microsoft to keep up with their commitments?  Let us know what you think in the comments.
