I disagree with Tony here. But he knows that ;)

Relying on the default exchange bindings is perfectly fine. They are in 
every 0-* AMQP spec and are widely supported by brokers. By contrast, 
attempting to manage these bindings (i.e. bindings to the default 
exchange) explicitly is prohibited by some versions of the spec and thus 
not guaranteed to work.
