reasonable to resend post-delivery. In that case, you'll have
Resent-* fields prepended to the message which may already have a
Return-Path. It will get a new Return-Path when it is delivered to

as previously noted, resending might not use SMTP))
the mailbox in the Resent-To, and that will be the MAIL FROM of the
resender.
Maybe there's an argument for removing a Return-Path before
prepending the Resent-* fields, but that's a different discussion.
Sounds reasonable. Maybe resending and the Resent- fields could be
moved to a separate document, which could more fully discuss the
issues relevant to resending (which transcends the message format per se).
