I am so strongly against that. There is already a standard header to do
just that! Why reinvent it?

Reread this paragraph:

This would allow filters like SpamAssassin to pick up the envelope-from
used at each step of the chain, which is very valuable especially when
intermediate steps tend to rewrite it.  (For example, fetchmail makes some
incorrect assumptions, and will add an *incorrect* Return-Path header if
an X-Envelope-From header exists, even from an earlier handover.)

Key phrase: "the envelope-from used at each step of the chain".

In this situation:

        SENDER -> FORWARDER -> RECIPIENT

There is currently no way to find out what the env from was at FORWARDER
if it has been rewritten -- as it would be for a mailing list or an
SRS-compliant forwarder.
