I don’t see it as a bad thing, if they ask me to verify my age via a driver’s license I’ll just delete my account, none of them are that important that I would give them a copy of my identification.
The legislation actually doesn’t allow them to require you to identify by sending them your licence. I think they’re allowed to request that as one of the options, but it cannot be the only one.
It sounds like the accepted options will probably be either facial recognition via third-party service (can’t wait to do that by pointing my phone at a video of a person on YouTube staring at the camera, like I did for a second backup Gmail account) or an official government age-verification service…which may or may not keep your identity from being tracked through the use of blinded tokens.
