That is a seriously dead draft written by Wayne Schlitt many many years ago:
draft-schlitt-marid-spf-from-hdr-00 (2005)

Inventing something "better than PRA" is doomed, PRA is as good as possible,
and as we know not good enough.  We had similar troubles in the DKIM WG with
attempts to do "something interesting" with the From header...  Until folks
started to grok the Resent-From: details, or the required Sender: if there
is more than one From: author.

This is a hopeless case, the only clean solution would be a "PRA", and nobody
wants the "PRA", notably 5322 and 4409bis do not really support the concept.
