Ale, FWIW, we're sending tens of thousands of FBL reports per day using the DKIM-FBL mechanism. I need to work on an update to the draft based on experiences.

There is ARF, by the late J.D. Falk, a competitor of XARF; both specify no canonical recipient and are thus subject to rejection by abuse team mailboxes that don't accept attachments. Then there are the DKIM and SPF failure reporting, that nobody uses. There is also Alex's DKIM FBL, never seen, just published the record now.
