Unlikely to happen, it's just not how they operate. Instead they will create a government registry where any legal entity can register their integrity attestation keys, with oversight by a bureaucracy in a process that takes 6 months and €100,000. Apps will be required to use the registry but still allowed to block attestations they don't like, and any attestation key that leaks into open circulation (such as FOSS) will be blacklisted in the registry because it no longer attests anything.
Exactly. There is no actual value provided by attestation that banks actually need. Banks have websites that work in web browsers, and those typically provide 99% of the functionality of the app, and yet the app demands attestation.
