Bear in mind that queues don't perform routing, only exchanges route

I'd be surprised if intermediate topic exchanges are significantly
faster than a single topic exchange, but the best way to confirm is to
test this with your own topics and workload and make the comparison.

A different possible motivation for intermediate exchanges is that it
might make administration more manageable.
