Hi Justine, Thanks for the well written KIP, this looks like it will be a useful addition.
Overall the KIP looks good to me, I have one question/comment. You mentioned that setting the `producer.id.expiration.ms` less than the delivery timeout could lead to duplicates, which makes sense. To help avoid this situation, do we want to consider a default value that is the same as the delivery timeout? Thanks again for the KIP.
