The issue is less about having an ID on file, and more about verifying ID. In a world of excellent real-time deepfakes, how would GitHub verify ID at scale?

A fake ID is pretty easy to create, along with a fake face for a video chat where you can hold up your fake ID.

An idea might be to require a financially meaningful deposit to pursue an account recovery like this. The deposit would be forfeit if the identity verification failed.

Though now that I write this, it creates a perverse incentive for a company to collect deposits and deny account recovery.
