I do something like this in some projects of mine.

RabbitMQ is completely happy to do this. On the other hand, literally every python client library would fall over and/or wedge forever periodically. Celery in particular was a flaming pile of garbage (at least circa 2018).

I wound up vendoring the best of the bunch (amqpstorm, fyi), and adding a bunch of additional logic to handle all the various corner cases. That, plus a bunch of careful thought about how the queues are structured, and I've been pushing millions of messages a day without issue.

I wasn't able to get a lot of my changes upstream due to the extent I had to alter the assumptions the library made about control flow.
