Please update your title to remove the misinformation about the bill, specifically calling it "OS-level ID verification" is not even close. It's not got anything to do with personally identifying information or any actual verification of age information.
It's actually an incredibly privacy conscious method of doing what it is trying to do, which is to allow parents to set up a child's account with their age information on a device and have that age bracket information passed to websites and applications. That way, it makes it harder for a child to bypass age-restrictions, but without requiring dangerous age verification methods such as ID or face scans.
The watchabilty thing actually makes stuff nearly unwatchable for me because I like to, you know, pay attention to the movie I am watching. They have to make the characters so one note and cliche so that half-brains can pick up what's happening in the film. They beat you over the head with everything but don't bother closing up plot holes because they think you weren't paying enough attention to see them.
