I want to develop a new driver for oslo.messaging to use rocketmq in openstack environment. I wonder if the community need this new driver？

There is a larger discussion around adding a driver for NATS (https://lists.openstack.org/pipermail/openstack-discuss/2022-August/030179.html).
Maybe the reasoning, discussion and also the PoC there is helpful to answer your question. I suppose you are also "not happy" with using RabbitMQ?
