There is 95% of deployments using rabbit because RabbitMQ serves the middle of the Bell curve of the use cases perfectly well. For OpenStack to be ubiquitous, we need to extend beyond our comfort zone of use cases and support technology that will let us address those. I see zmq has an enabler for that: it will solve other classes of problems triggered by extreme use cases. So yes, obviously RabbitMQ dominance should (and will naturally) drive the development and maintenance efforts. But we should at least try to not make the lives of those who explore new trails (and reach to new use cases) miserable. -- Thierry Carrez (ttx)
