Re: [webauthn] Give each authenticator a GUID and add an option to CredentialsContainer: create method to return this GUID if user permits (#2263)

This proposal seems very similar to what Device Public Key (DPK) aimed to be. If you weren't here for that, DPK was basically an additional, attestable pseudonymous device-bound keypair that could be returned during registration and authentication to help RPs understand when they'd seen a device before.

For numerous reasons related to potential user privacy issues and RP misuse, DPK never took off. The WebAuthn community has collectively moved on from DPK to work on other, better signals that have less risk of negatively impacting the user's experience.
