Brazil's authoritarian age verification law became active this month. It won't be implemented by GrapheneOS. Complying would require integrating a mandatory process for each user where a third party service checks government identification and confirms a match using the camera.
It doesn't stop there. It would require keeping data for auditing and providing a token for connecting age verification checks by apps and websites to the data. The law is a privacy disaster and exposes minors to being exploited by leaking their age bracket to apps and websites.

@GrapheneOS

is it a good idea to have a "age proxy" like the mechanism for filesystem access "spaces"?

when an app doesn't run unless the OS tells it the user is id-verified, then grapheneOS could say yes, the user is, even if the user hasn't done the process because they don't want to risk their biometric information

I'm no expert, just thinking aloud
