ok, thanks this also makes sense.

What eventually happens to message 2 in sequence 1,2,3,4,5 if the
other messages in the sequence have been acknowledged, (but not 2)?
What needs to change in order for message 2 to be received again by
the consumer?

I think that in the case of some errors in the running application the
consumer client did not acknowledge some messages. I was secretly
naively hoping that such messages would be injected by the server into
the sequence at a later point after some timeout not having received
the ack.
