To be fair on this: The main driver behind this is security and having

Of course saslauthd will need SOME access to the remote (back-end) IMAP

But this can also be accomplished by having the front end Postfix
authenticate on the
Dovecot back-end by setting it up to talk to the auth process via an
ALSO on just one IP port.
