Yes! This is the way, give parents the ABILITY to advertise the users age to browsers, apps and everything in between. Only target cooperations, do not target open source projects. Fine websites for not using this API (ex: porn sites). Assume an adult if not present.
No. This is not the way.

Accounts and Applications to services that provide countent are set to a country-specific age rating restrictions (PG, 12+, 18+, whatever). That's it.
None of the things you mentioned have any point to concern themself with the age or age-bracket of the user in front of the device. This can and will be abused. This is very obvious. Think about it.
This is a great solution to the stated problem. The issue is that nobody is actually trying to solve the stated problem. This is a terrible solution to the real 'problem' which is the lack of surveillance power and information control.
This is what I think. I saw someone else on HN suggested provide an `X-User-Age` header to these sites, and provide parents with a password protected page to set that in the browser/OS.
Responsibility should be on the website to not provide the content if the header is sent with an inappropriate age, and for the parent to set it up on the device, or to not provide a child a device without child-safe restrictions.
It seems very obviously simple to me, and I don't see why any of these other systems have gained steam everywhere all of a sudden (apart from a desire to enhance tracking).

Recent posters here are clear that porn sites are setting every available signal that they are serving adult-only content.
According to them, you are targeting the wrong audience.
Facebook/Instagram studying how to get young users addicted should be of greater concern. I have my doubts about the effectiveness of age-based blocking there, though.
