These new well-defined rules provide a mechanical procedure for determining whether the encapsulated message body is the "same", provided that the full message is DKIM-verified. It's arguably more the "same" than a normal mailing list posting with a list trailer added, because the list trailer under these rules will belong to the list's part of the composite message. Only the headers are different, and they were going to be different anyway, given DMARC's strict requirements on the From header.
