The problem is that there's no limit to how people want to configure
their outgoing mail.

And using just the envelope-from might be correct for your use case, but
it's not, in general, very useful.

If we want to add something like this to smtpmail, it has to allow a
full range of customisations for how to determine the server...  and
that's best done in the MUA, in my opinion.  Which is why it's
implemented via a header so the MUA can do this.
