I won't speak for anyone else, but when I say that OpenStack should
be "one thing" I definitely don't mean "the only thing." What I
mean is that someone selecting several OpenStack components to use
to build their stack should have those components behave in similar
ways, and use similar deployment and end-user patterns so that once
someone figures out one component the next is easier to figure out.
It would be great if those components were able to integrate directly
with other tools not produced by the community (serving volumes to
containers with Cinder or authenticating non-OpenStack apps with
Keystone, for example), but that's secondary to the components
produced by our community actually working together, in my mind.
