Is it really any different in practice? TPM is installed in basically every computer used in basically none. Even though its been a uniquitous "standard" for two decades its effectively impossible to correctly do attestation. Similar arguments could be made for UFI and similar. Just because some can write code for it only a handful of major suppliers actually do. Are those any more accessible than this?
