Until it's possible to physically link a passkey to a device like a yubikey I see no security "benefit" to giving single permissioned access to credentials to large tech companies. It's a single point of failure even worse than trusting a password management company like OnePassword etc. I'm still holding out for a self hosted or federated version of passkeys, potentially similar to how more complex forms of crypto custody exist - similar to multi party computing (MPC).
