How does a passkey differ from a password from an attestation POV?
Also, passwords don't have rejecting [optionally, for now] non FIDO certified devices as a part of the spec. You'll have to use a Trusted(tm) passkey manager.

Sorry, I may not be parsing this correctly: Are you saying that security requirements for pass[word|key] managers is bad? Or are you saying that they're bad because it means open-source solutions can't support passkeys, as @Ridj48dhsnsh suggests?

What will likely happen is that many services will only accept passkey managers that have been blessed by big tech and locked down to the user. You're not going to be able to authenticate with your bank using an open source implementation.
