I attestation should be abolished altogether. An app should have absolutely no way of knowing what kind of device it’s running on or what changes the user has made to the system. It is up to each individual to ensure the security of their own device. App developers should do no more than offer recommendations. If someone wants to use GrapheneOS, root their device (not recommended), or run the whole thing in an emulator, a homemade compatibility layer under Linux, or a custom port for MS-DOS, that should be possible.
