It would also restrict you to using a Return-path which is valid for

access to submission port on home server, e.g. outgoing TCP 587
blocked or network unreachable).
So what you're saying is that any mail server should be able to source
messages from any mail user using any email address in any domain.
Sorry, that's not a reasonable desire in my opinion.
what's unreasonable is trying to use IP addresses as authentication
tokens, or expecting applications to know about network topology in
order to route messages.
