Don’t get me wrong, I’m all for privacy. But between setting up the birthdate when creating my children’s local account on their computers, and having to send a copy of their ID to every platform under the sun, I’d easily chose the former.
I’d even agree to a simple protocol (HTTP X-Over-18 / X-Over-21 headers?) to that.


Well if it’s not mandated (on the OS side that you refer to) then sure.
I mean it would be opt-in. Me and you wouldn’t ever get it and websites and developers wouldn’t be burdened by it. That’s the point.
No problem with your excerpt there either.
