Unfortunately I didn't participate to the original design of the system so I don't know which is the underlying idea.
We can have a lot of temporary queues (like temp_queueA) and a lot of messages at the same time to have a single exchange (the default one) to deliver those messages could not be a bottleneck ?
So maybe the original idea was to design the RPC using separate exchanges for having more scalability?
I don't know it's just speculation.
