It WOULD be nice if it only got used appropriately. But in 2026 its just one more metric to narrow down your profile for advertisers. Wouldn't it be convenient if you could just opt-out of tracking with a convenient API like the literal "do not track" header in browsers? It exists, but none of the people who SHOULD use it pay it any attention except as, ironically, another metric used to track people.

Not to mention that computing is a global thing, and in order for this to be useful it would definitely have to be providing more specific information than just a bool. Maybe chats require 13+, but pornography requires 18+. Maybe those ages are different based on location. All advertisers would need to do is ping the various different checks to get your actual or at least very approximate age.

This kind of thing is a slippery slope, and its ripe for abuse by doxxers, advertisers and big brother himself. Burn this with fire. I'm totally in agreement with the others that suggest stuff like this should b just get banned from getting introduced and reintroduced constantly trying to sneak it in as a rider or hidden provision. The people DON'T want it.
