I think ideally if there's tooling for this it should have both a
verification feature like you mention and also be supported by b4 mbox
so that you can say "b4 mbox ${COMMIT}" or whatever and have it download
a mailbox like can currently be done with a message ID.  That'd keep the
usability we currently have, the tool could look in the message for a
link and use that if it needs it.

What might be especially usable for applying/publishing would be
something that can be used either in a hook or more likely in scripting
that'll take the Message-Ids from git that people currently use to
generate the Link: tags and discard them if whatever the tool usually
uses to find mail archive links works without them, or rewrite them into
Link: tags if not.  The tool could emit the warning you suggest when
leaving the links in.
