Tracking trunk. If the messaging branch has already landed in Nova, then
this is a moot discussion. Otherwise we'll still need it in incubator.

That said, consider if messaging wasn't in nova trunk. According to this
policy the new functionality would have to wait until it was. And, as
we've seen with messaging, that was a very long time. That doesn't seem
reasonable.
