If you make the queue auto-deleted, it will be removed when the last consumer goes
away (if there ever was at least one).

Ignoring restart scenarios for this discussion, RabbitMQ never deletes bindings unless

1. You use queue.unbind
2. A queue or exchange for the binding is deleted

It's also possible to check how many active consumers a queue has
by issuing queue.declare and inspecting the response (queue.declare-ok).
