i.e. this doesn't require age verification at all

just a user profile age property

so you have to give apps and similar a 13+,16+,18+,21+ hint (for US)

if combined with parent controls and reasonably implemented this can archive pretty much anything you need "causal" age verification for without

- any identification of the person, its just an age setting and parent controls do allow parents to make sure it's correct

- face scans or similar AI

- device attestation/non open operating systems/hardware

like any such things it should IMHO have some added constraints (e.g. "for products sold with preinstalled operating system", "personal OS only" etc.)

but this gets surprisingly close to allowing "good enough privacy respecting" age verification

the main risk I see is that

- I might have missed some bad parts parts

- companies like MS, Google, Apple have interest in pushing malicious "industry" standards which are over-enginered, involve stuff like device attestation and IRL-persona identification to create an artificial moat/lock out of any "open/cost free" OS competition (i.e. Linux Desktop, people installing their own OS etc.).
