Sure, that information should be kept - but should Gnus dictate that
it be kept in the message header, when it isn't necessarily part of
the message?  This mandates lossage, which is unfortunate.  Maybe
-request-move-article functions could set up variables containing the
envelope sender and delivery time (that's what's in the From_ line,
right?) and then the receiving -request-accept-article function could
put those values somewhere appropriate for that backend's storage
format.  (It would be cleaner to pass the values as arguments, but
that would require changes to Gnus itself, in the accept-form
business, instead of just the backends.)  For maildir, the delivery
time is the file's last-modified time.  In general, the envelope
sender isn't necessarily stored anywhere, although when qmail delivers
a message to a maildir, it adds a Return-Path: field for the envelope
sender.
