I agree that we should keep this. We don't actually support rabbitmq at all except to say that it theoretically works, and good luck. There is no harm in mentioning how to use a vhost.

This is not part of our official documentation, but just side-documentation for developers or anyone else interested in advanced usage. This is "use-at-your-own-risk" documentation that we don't advertise or necessarily even maintain. Hence being in the "playpen".
