That still doesn't explain why you're using it though. It is for
intents and purposes, a semantic NOOP.

I'm slightly confused. You're now talking about about the sending side
but your code beforehand was an example of a consumer.

As an aside, on the sending side, you could use the immediate or
mandatory flags to get the broker to *indicate it's inability* to
deliver a message without you having to use a transaction, but I'm not
sure those are the semantics you want.
