Everything is going to contribute to tracking, though. It's really hard to ensure that data doesn't leak.

Example proposal: sites attach an X-AGE-RATING header to pages and browsers only render the page if X-AGE-RATING < USER_AGE.

Exploitable Issue: Send multiple requests from one page for various style sheets with different X-AGE-RATING headers. The ones that get loaded give you all you need to find the user's age cohort.

But, the unique combination of things like your screen dimensions, number of threads, charge percentage, default languages, available fonts, etc already makes tracking possible. I don't know if adding one more - carefully chosen feature - would really make the situation that much worse.

no, and you can read through other comments here and on the many threads of the same topic for proposals which have no tracking.
