I think it is meaningless only when a client has only one active 
subscription. But if a client has for example both a temp-queue 
subscription and a normal subscription on the same connection, the 
subscription header in the MESSAGE frame is necessary to route the 
message inside the client.

So I would prefer a subscription header too, as my Delphi Stomp client 
library for RabbitMQ could support temp-queues without workarounds.
