>We have now gone from having to “redo everything” to being asked to switch to a passkey by a grand total of one website.

Yeah right.

When passkeys were rolled out, I was told it's OK because "passwords are always going to be required to be an available alternative".

Now we've moved the goalposts to "it's just one website".

>Sometimes the new thing really is just better.

And sometimes your backpack is stolen when you're traveling, with your phone and laptop (happened to me in Poland), and you need to log into your accounts while having none of your devices or your phone number available.

Pray tell then what.
