That's my current impression as well. The companies involved are more interested in making themselves the center of the universe than in collaborating to address the rather obvious user and developer experience issues. Nobody seems in a hurry to do this. It's the same reason why previous attempts at federated identity have fizzled out. Both MS and Google loved the idea of the whole world using them exclusively as the only identity provider but then balked at the notion of their users using an identity provider that wasn't them. Passkey is a repeat of this. Apple loves the idea of people using iphones to identify with whatever. Android, not so much. And MS of course wants to keep a tight grip on passkey's used to sign into Office, Windows, etc.
