What I’m trying to say is, that’s already the default running mode of a modern browser with the maybe exception of ad blockers on some. They already come with all privacy protections that don’t compromise compatibility. DNT, being a specific feature enabled by a very few people, doesn’t make sense to be reshaped into entirely something else like ad blocking (which is way beyond tracking protection and not necessarily mutually exclusive with it) or disabling of third party cookies (which has auth related consequences).

The conflation of semantics isn’t worth it, and may even be harmful. I totally disagree with the proposal.
