+1 to jay's comment.

I see Nova's mission as providing a solid interoperable API experience
to on-demand compute resources. Right now, thats happening best by
keeping things in tree, but we are doing work to make other options

I actually see the existence of projects such as Cinder, Heat and
Magnum as success stories born out of Nova saying no to expanding our
scope (and in the case of Cinder, actively trying to reduce our
scope). I hope more of both of those things will happen in the future.

If we had accepted these efforts into Nova, they would not have had
the freedom they get by living inside OpenStack, but outside of
Compute. Something the big tent makes much easier to deal with. I
don't think they would have gained much by being inside the compute
project, mostly because we are all crazy busy looking after Nova.
