The crucial question is whether any messages that the publisher has 
received a confirmation for are lost. Obviously if the cluster is never 
restarted then any enqueued messages are lost. And, similarly, any 
non-persistent enqueued messages would be lost even in the restart. But, 
assuming the cluster comes back up, any persistent messages that have 
been confirmed to the publisher should still be there / get delivered to 
consumers.
