Easing local control is what that law was about (and it did think far enough to only include user facing). If there wasn’t a global tendency to move towards surveillance and identity verification I’d be all for it. As it is I have some reservations about slippery slope.

The law doesn’t require identity verification. It requires the OS to provide the age group of the user (set at install) to programs running on the OS. Something that, if adopted widely, would immensely help with allowing parents to control access (i.e. if they decide their kid should be able to see everything, just put them in ths age group for that, similarly they could also do that and manage it the same way as they would now. Or if they’re lazy as many parents sadly are, there is at least some enforcement of age control that someone thought about, without giving up any identifying info beyond an age group). Yes it could be circumvented somewhat easily, but as far as I see it that’s always a feature. A child being exposed to something accidentally has very different implications than actively trying to access it.
