Just a random thought but would there be any value in adding an 'unsubscribe to all' function that can be called prior to destruction? The unsubscribes would be sent to the mqtt client to be processed (or not processed if the client is also being destroyed) to free up whatever subscriptions the RR had. Would be fire and forget with no wait on acks. This may be useful in a use-case where someone is creating and destroying multiple rr clients over the course of a connection with different names.

That's what aws_rr_subscription_manager_clean_up does
