Thank you for this information, it's very helpful. I've shared this with the team internally. 

Out of curiosity, did you try the suggestion mentioned here on the page that you linked to and did that allow 1Password to save or sign in using a passkey?

I can confirm, when I run in Safari Development Mode Console "delete PublicKeyCredential.prototype.toJSON" before clicking on button "Verify Passkey on device <my_device_name>", then clicking on it -> 1Password's "Sign-in with Passkey" popup appeared, again clicking on it (confirmed on phone) and everything worked as before -  I logged in successfully.
