Comment 1 for bug 1579595

in step4, we can use GET /v2/queues/{queue_id}/messages/{message_id} to get the message after claim expired. So the request works well.

And the "href" include a claim id in a unclaimed message. I think it is useful to indicate that whether this message is a new one or has been consumed before.

So IMO it's not a bug in this use case at least. But maybe it will confuse users more or less. Perhaps we could do it in a better way?
