They don't contain much information and don't talk about thresholds
though I haven't seen any for a while having successfully taught dspam
about them.

This is the part I don't really understand.

You're in an amazing position.  You have thousands of people who have
potentially better spam filtering systems than you do bouncing mail they
think is spam at you.

If you count per message-ID who bounces which mails you could improve
your filters based on some threshold of how many people bounced that
mail.  Especially given you do process bounces automatically via your
script that cause the original post.

Instead, masochistically you send out contentless pings that your
subscribers dislike.  I don't get it.
