It won't just be them. I foresee Cloudflare and other CDNs offering a free checkbox: [] Require age of majority verified user
And it will in turn depend on Secure Attestation, Web Credentials, and other recent W3C work to provide proof that you're the registered owner, age of majority and verified by thumbprint or other biometrics, running an unmodified device. Your ID might be escrowed with your OS vendor, email provider, bank, ISP, or even Twitter/X, who knows. Either way, as an end user you'll be mollified that you don't have to provide your ID to the adult site, and the adult site will be happy that they don't have to implement any of this themselves.
And, of course, this will mean that an intelligence service could have ironclad proof of exactly what person visits what website, effectively killing a lot of online anonymity.
