I would expect passkeys to be a massive liability for Apple in case they get breached. Why would they even want access to them? Do you think they want access to your accounts?
I think they want to provide the "I forgot my password and lost all my devices" convenience. People hate loosing their data and loosing access to a lot of passwordless services would be a nightmare. In general I'm super weary of anybody who promises to have no access to my account and then offers any reset password functionality.
