Waydroid is not a private or secure way to run Android apps. It uses an old fork of LineageOS and throws away most of the privacy and security model with how it's implemented. It does that to run Android apps on top of a much less private and secure base OS. Compatibility is far worse and it in no way avoids the Play Integrity API checks. Most banking apps do permit GrapheneOS and some of the apps banning using a non-stock OS or non-GMS devices with the Play Integrity API have explicitly permitted GrapheneOS via hardware attestation including Swissquote. Banks have no reason to ban GrapheneOS since it has all of the standard privacy and security model combined with major privacy and security improvements. They're often willing to permit it once they understand what it is and how they can verify it with a standard Android API. Convincing every app using Play Integrity to do this case-by-case is painful and unrealistic, but regulation can require permitting secure alternatives meeting defined security requirements.
