I kind of like the idea, but fear this would not be viable for two reasons - although interestingly they are somewhat opposed: 1. DNT’s already failed as a opt out since less scrupulous actors either ignored it, or used it an an extra tracking signal (!) 2. More scrupulous actors would likely take the view that DNT can’t express adequate consent for tracking (no granularity or evidence of informed consent to privacy policies).
