There are still a lot of questions I'm not clear with passkeys. How do you recover your keys if you lose your hardware? What happens if you lose your phone and have no extra trusted device? There will be no more phone number, and no more trusted device. Most MFA implementation, which heavily rely on phone number, will no longer work. And, for Yubikey, how do you backup? Do you need multiple Yubikeys? Do you need to manually make a copy of every keys? How do you know if the copy is synced with the main one?
