Hey there, it would be amazing to collect examples of dealing with DLQs and showcasing different strategies around it.

One way of doing it could be the following:

• have a WorkQueue stream with no max age (ensures message is only removed if explicitly acked by a consumer and it's not removed by TTL)
• use a consumer with infinite retries
• once a message hits a certain retry count:
  • sync publish into another stream, with a unique subject requirement
  • only if the sync publish was successful, Ack the message
• otherwise just process normally

But there are definitely more ways to do it.
