I’ve never seen an implementation where passkeys deleted my password or could lead to a situation where it was locked out. They usually just bypass the password+2fa dance when functioning, and otherwise just don’t matter if they don’t function. (Well perhaps except home depot, where it gets mad at me every time I use a password and tries to install a new copy of the same broken passkey as last time, for my convience)
If that's so then what actual security benefit is derived from it?
Of course the sites presumably will flip the switch at some dreaded point in the future where you can no longer circumvent them, but at this rate it may take a long time to reach a use by majority of users.
This. I use passkeys on mobile os to more quickly access commonly used services, but they do not completely replace other passcode+2fa credentials.
