Open Stack

Sorry for the late reply. Your proposal is interesting. According to
the previous discussion of works on zeromq driver, we should first
make zeromq driver completed for all the OpenStack projects and CI.
During these days, lots of patches are submitted to upstream. But some
critical ones are still in review, [1], [2]. I'm also working on
devstack support and documentation [3-5]. So, IMO we should make it
maintainable in the current release cycle. And we can try to improve
it in the next release cycle.
