Here's the most readable reference to playing favorites on passkey vaults I could find from the FIDO Alliance (the previously mentioned 'cabal of evil').
See Section 2.2: "Validating FIDO UAF authenticator attestations against the configured authenticator metadata to ensure only trusted authenticators are registered for use. "
And Section 2.3: "Verify attestation assertions made by the FIDO UAF Authenticators to ensure the authenticator is authentic and trusted. Verification occurs using the attestation public key certificates distributed via authenticator metadata. "
Basically, Relying Parties (the sites you are logging in to) are expected to allow/disallow certain passkey authenticators (the devices or software that hold your passkeys), based on registration and trusted lists. The FIDO Alliance can use entry into those trusted lists as a cudgel to force compliance with the standard. Effectively, the standard is that users must be locked into to proprietary ecosystems, unable to escape.
Here's KeePassXC being threatened with blacklisting over granting users control over their own data:
