I don't know why / how messages should be ordered. NSQ is a message queue and not a log. Some messages take longer to process than others, and some messages need to be re-queued and re-tried out of order, and that is a very common use-case.

I would love to be able to use a distributed log like Kafka/Redpanda since it's HA out of the box, but it simply does not fit that use-case.
