I can definitely relate to the problem that it's trying to solve. We
have a backend that has both thin-provisioning and compression. Right
now, we have no easy way to filter which storage node that a volume
should be created on if compression and thin provisioning is to be taken
into account.

That being said, I'm not sure about the implementation as such. I could
see how it needs to remain flexible to accommodate a bunch of different
types of drivers.

I suppose that it's a start.
