It means requiring the age restricted device to validate against the existing rating headers “Adult” websites already set, versus requiring the client to upload their personal information to validate their own identity to the “Adult” site. FWIW, iOS already does this. If you have parental controls enabled and a http request is made with a response that sets ‘rating: RTA-whatever’, webkit will refuse to render it. This is a good thing. The texas law blows, same general category of “harass the user instead of embrace the platform” as cookie banners.
