One way to get more control over what clients are doing is to insert an 
AMQP proxy. Proxies are great for dealing with authentication and 
authorisation, load balancing, throttling, etc.

In this specific case you could have a proxy that inspects all 
queue.declare commands and either rejects those w/o an appropriate 
x-message-ttl or inserts the x-message-ttl on the client's behalf.
