Pardon my ignorance, but isn't the scenario above exactly the same as a
"typical" mail transaction?  From what I understand, SMTP AUTH can be used
to allow users to send mail through your server from outside your server's
configured "trusted" netblocks.  However, since your trusted netblock
configuration are not visible to the outside world wouldn't an
authenticated Received list look exactly like a "non-authenticated but
inside the trusted block" Received list?

Additionally, even if qmail did indicate that the transaction was via SMTP
AUTH, SpamAssassin really couldn't trust that information in the Received
line.  A spammer could simply inject a fake Received line with the AUTH
markup.  SA really can't trust any headers other than those that the end
MTA (or any configured trusted servers) have added, right?
