Provided you know the secret key to a government-issued certificate. Making it impossible to copy said certificate is not really a requirement for identity verification.
Rooted, wildly insecure devices can pass the attestation easily: https://magisk.dev/modules/play-integrity-fix-inject/
Safe, updated devices cannot unless they permit Google to run their surveillance services in the privileged, unconstrained mode.
I think we need some fingerpointing that EU officials strive to avoid.
Authorities/anyone could verify that it's not counterfeit. And photo should be checked anyways to match the person.
So I also don't see the need for attestation. For ID check it should be ok without. For signing stuff ofc it is not resistant to copying. But EID smartcard function already exists.
While it's dramatically worse than devices Google refuses to certify (ie these not running their spyware as privileged services).
Because Google then abuses its position to inject unremovable spyware with elevated privileges into the phone which the user then can't defent against without making the phone "unsecure" and thus unsuitable for these apps.
If these apps really need a smartphone, I'd at least want it to be free of ad-related garbage in the system. I'm fine with not being able to flash a custom ROM on the smartcard as it doesn't contain hostile software.
Now if even Apple starts showing ads, there's no other choice but to restist this..
