oslo.messaging integration development

Hi everyone, I find Apache Pulsar is very popular in MQ area, especially in clound native area. Is there any body integrate this MQ to oslo.messaging? Said to the truth. RabbitMQ developed in Erlang has very little source code level material, Qpid has very little operation practice in the internet. Kafka only support notification in oslo.messaging. I think the Apache Pulsar is clound native based. It may enforece the big scale in extension about Openstack deployment.
