I think that would be a good idea. The other legacy bacckend that we may 
need to care about is xenfb... not so much the framebuffer itself, but 
the mouse and keyboard aspects. The XENVKBD and XENHID drivers expose PV 
mouse and keyboard to Windows instances so it's be nice if we can avoid 
the backend withering away.
