I haven't had time to follow this thread, but in case anybody hasn't
noticed, multihop return path rewriting takes us right back to 1982.
This quote is from RFC 821:

      The <reverse-path> can contain more than just a mailbox.  The
      <reverse-path> is a reverse source routing list of hosts and
      source mailbox.


and later, this:

      Conceptually the elements of the forward-path are moved to the
      reverse-path as the message is relayed from one server-SMTP to
      another.  The reverse-path is a reverse source route, (i.e., a
      source route from the current location of the message to the
      originator of the message).  When a server-SMTP deletes its
      identifier from the forward-path and inserts it into the
      reverse-path, it must use the name it is known by in the
      environment it is sending into, not the environment the mail came
      from, in case the server-SMTP is known by different names in
      different environments.
