IMO auto-delete=true gives undesirable results when queues are created
implicitly on SEND - messages would be queued until the first subscriber
arrives, but if that subscriber disappears before it has received all
the queued messages then the remaining messages are lost.

OTOH, auto-delete=false forces the user to step outside the confines of
STOMP and use ordinary AMQP operations if they ever want to delete the
implicitly created queues and thus free up server resources.
