Personally I think the rk requirement is just fine, the long-tail goal of Passkeys is to simply credential management for users and the UX of key wrapping stands in opposition of that. Having a security key handle unlocking your platform authenticator/password manager seems to be the middle ground that's being driven towards, and as somebody with multiple YubiKey's I'm perfectly fine with it.
