I would like the rule to be that a null return path MUST only be used for an auto-response (which includes DSNs and other kinds of bounce) and MUST
only be used with a recipient address which is the return path of the
message that triggered the auto-response.

it's not going to happen. there are too many other kinds of messages for which a null return-path is valid, and this is an incompatible change to a protocol that has ~25 years of deployment.
