Well what is your SLO around message delivery? If it's "a successful response means a message will be delivered at least once and in under X time" then you need to verify that message has been durably committed to multiple machines in all of your availability zones. if it's just that the message is durably committed or the SLO on delivery is long enough, then you can drop the multi-as bit.
