I mostly agree with you, but having spent a good part of my career dealing with data integration patterns, I'm all too familiar with the problem of missed messages from the consumer (or failed-to-send messages from the producer) that results in something downstream being in an incoherent state. The simplest fix for that incoherent state is often to also poll periodically, or something similar.
