Your analysis of the behavior of the PMDF mailer is incorrect. PMDF does NOT
send error returns messages to the Reply-to address in the header, or to
any other header address, for that matter. It sends failure notices to the
envelope From: address, which is not part of the header at all. The envelope
From: address is controlled by the next hop upstream, and it should be
set either to the originator's From: address or some special intermediary's
From: address, NOT the list address!

There has been lots of talk about using Errors-to: fields at various points
but it is not part of any standard I know of, so having one mailer that
supports it is of little use.

There is also some debate over how and when the Envelope From: address
should be modified to point at an intermediary. We have been discussing
implementing just this feature in PMDF for some time.
