IIRC there wasn’t anything about the OS needing to validate the info, just ask for it at setup and provide it when requested. Part of me wonders if this was just an attempt to stake out a position as to what a law of this sort, that still respects privacy, might look like.

I dunno. I don’t love it. But if a dumb age-range flag became “the thing” to check, well, that’s be less invasive than uploading an ID or something.
