The concern is that OSes which don't implement the feature will be outlawed.
Movie ratings don't outlaw movies and actually provides a good framework: instead of mandating that OSes implement this, publish a client-side filter spec that OS devs can choose to implement. And if they implement it, their OS gets a label like "PG-capable". Then make it illegal for minors to possess a non-PG-capable device.
