I hope that at some point this is not developing to remote attestation when only "permitted" devices can use the models.
Hardware 2FA is not a new concept and is recommended by many people for many purposes. Only the authentication token is attested, and that is the purpose of an authentication token.
If the best models are so anticipated that people do anything to get them, seems like remote attestation fits perfectly here. There is no need to use it for lower quality models which are used by masses. Instead, it even works for marketing narrative where they do everything they can that their great models are used only those devices they allow, and no <name your country> can't easily use them. Maybe even helps setting higher price.
