Android has an accessible hardware attestation API already (https://developer.android.com/privacy-and-security/security-...). It's what powers the attestation API that GrapheneOS made as an alternative to Play Integrity and friends (demo app: https://github.com/GrapheneOS/Auditor)

It's up to third party app developers to choose what library to use, of course. A court case between the EU and Google isn't going to chance anything about the verification steps apps like Netflix or your bank might use, that will have to be a separate case.
