Having implemented Passkey-only account creation (and management) I would absolutely disagree. I think that Passkeys can greatly streamline the process. The iOS Passkey flow especially feels as simple by default as the "Sign in with Apple" flow (with the ability to customize it with smart password managers in a way you'd never be able to with "Sign in with Apple").

That's partly because Apple sees it their job to migrate people away from OIDC-style signups, for privacy reasons if nothing else, and towards Passkeys, so their UX team is doing a remarkable job trying to reduce friction.

What's Google's interests here? Are there intentional reasons the Android and Chrome Passkey flows don't "simplify" the account creation process enough? It's easy to be cynical here, and seeing them as orthogonal concerns also feels like muddying waters that shouldn't be muddied right now.
