Just to pause for a moment at that particular mulberry bush, recall
that pip needs a real dependency solver and so we don't actually
control the upper bounds of transitive dependencies. "That's all
well and good," you say, "we can just worry about our direct
dependencies and keep them all in sync in the requirements lists."
But now think about how we're trying to make some of the projects we
develop more broadly usable outside of OpenStack... just last week I
noticed that one of our transitive dependencies uses pbr, and is
not bound to the same version restrictions as dependencies we happen
to develop ourselves.
