But it is an assault on privacy. If "protecting kids" was the goal here they'd push for regulation that forces websites to return standardized metadata that then gets interpreted by the user agent which can be configured by the parent.
sigh If data brokerages, Meta, Google, and Palantir are all staring at you how is it possible to claim privacy is even possible? Like, you have to have a thing before it's possible to assault it.
Nah, that's a perfectly fine technical solution. Powers that be don't think like that. They understand pulling someone over to check their license, so something like that will do.
