Your points about extensions being optional and easy for browsers or authenticators to ignore (or be incapable of supporting) is a valid one. I don't know what a path forward is now...tell RP's to let passkeys happen and forget about `devicePubKey` since it can't reliably achieve its intended goal of supporting pre-passkey operation before passkeys deploy?

I think this highlights a flaw in passkeys: that now there is an avenue to phish users when originally the spec made WebAuthn-based authentication phishing resistant. Is that trade off worth it for an actual account recovery story for the consumer market?
