I wouldn't drop the idea because of that. In the case of the os-brick
library, there was common code for interacting with local storage
management in both Cinder and Nova. We recognized this and started the
os-brick library to move that code into one place.

Cinder started using it right away, but it was at least a couple cycles
before Nova started looking at it. I think that's perfectly fine. If
you are able to start a library for your own use, and it has good and
useful common functionality, then Nova can make the decision later if
they want to take advantage of it.
