With that approach the number of consumers must be exactly the same as 
the number of queues; if you have fewer then some messages won't get 
consumed, and if you have more then some consumers won't process any 
messages.

Furthermore, you cannot add/remove queues since that will cause some 
subsequent messages to get routed to different queues than prior to the 
queue addition/removal. They will then be picked up by different consumers.
