Although it appear stupid, maybe an OS level endorsement of user age is actually a more reasonable middle ground than delegating mandatory age verification to data brokers...

It still parents that usually buy the computers and set up the différents user accounts. So the responsibilities would be put back in their hands as machine owners to correctly tag kid's accounts. OS vendors would then only be responsible to accurately transmit this declarative information to requesting App/services.

Of course some smart kids are gonna find a way to bypass that (as any other mesure you can imagine, because kids are smart). But nonetheless we could have a good enough OS level declarative age for 95% uses cases and send to the trashbin all the age verification creep that is the current trend.
