Why are you even accepting this something like this should exist? What is the threat model that this is protecting against? How would it offer any protection against that threat? Why should everyone who is making any program need to ask about the age of their possible users?

In addition, the law requires that every developer of every application, commercial, FOSS, student, hobbiest, professional, or whatever verify the age bracket of every person who downloads and runs their program every time. Every time it is downloaded, every time it is run. Yes an API for this would be trivial to implement, but that’s not the point. The point is why the fuck should I have to face a $2500-$7500 fine every time some kid downloads my pong demo? Why the fuck should PyPI, GitHub, or crates.io have to get the age bracket of every user? Why should every apt request include an age flag? Because that is what the bill requires.
