Still not what I would call 'proper' queuing (IMHO!) because ultimately it's still just Kafka and just append only: you can't 'atomically acknowledge+delete' individual messages anywhere in the stream, you only dealing with offsets and that's a fundamental thing that has many consequences (e.g. you don't get ordering between batches) and also means that you will get re-deliveries in some scenarios that you would not have with a system that implements proper queuing.

I CAN drive a Ferrari to the grocery store.

Sure, it can do it. But it's not efficient or what it's good at.

I'm really unsure where the drive for this is coming from tbh. (cough CFLT share price since IPO, big enterprise customers cough) If this was so desirable, everyone would've jumped ship to Pulsar already.
