If you truly believe that the other end is non-compliant, or has made a mistake, then the correct response is to notify them, so that the responsibility both for advising the rest of the system or the user (or the tool author) of the error now lies clearly at that end -- both the error (if it is one) and the notification now belong clearly at the UA end.

Good point.  

I have no problem with separating the signal "is your communication compliant?" from "am I tracking your user (despite your attempt to send me DNT:1)?", and clarity on both is fine by me.
