@lukebakken I cannot think of a reason not to do it. rabbitmq-diagnostics consume_event_stream and rabbitmq-diagnostics list_* commands are the closest we have to a "two-way communication" and even they do not need a listener.

But we can tweak the RABBITMQ_CTL_ERL_ARGS default and see how well those commands that stream results (continuously or when there's a large number of, say, queues) do.
