I mean I like them in theory but they should just be passwords you can't easily copy from your password manager. You can export them, which I'm sure someone will trick people into doing, but that's somewhat different from being tricked into pasting ul0vek1tt3ns into legitimateapple-support.info.
As for sharing passkeys: never grabbed a friend's Netflix account? Had to log into your kid's college application page to confirm your income? Sign up for an appointment for your elderly parents? This is a thing people actually need to do, and value more than avoiding being phished. Believe me. It's not worth abandoning for "ok there is a possibility someone can be phished if the key material isn't protected by a hardware key and three layers of DRM".
