I tend to agree, although it's up to the oslo-messaging-core team to
decide what they want to support.

A general note on these sorts of conversations:

It's very easy to look at the state of OpenStack testing now and
say, "we must have integration test jobs for oslo.messaging!" Don't
forget that most of the work in this repo came out of Nova at a
time when there was no such thing, and we've only just settled on
good processes for managing third-party testing of that sort in
Nova, Cinder, and Neutron. We've been watching that work with
interest, but given the small size of the team currently maintaining
the library, it wasn't necessarily the highest priority.

That said, I know Mehdi and others have been working on setting up
integration test jobs, and I expect that at some point in the
not-too-distant future we'll need to discuss putting a rule into
place for these drivers just like the other projects have for their
drivers.  We don't yet have a sufficiently strong test suite to do
that, though, so requiring test jobs now would be premature.
