Yes, and there is an open source spec [0] that doesn’t require Google/iOS Attestation but “preferably” providers will make their wallet app available on App Stores [1]:

> To ensure that the User can trust the Wallet Solution, Wallet Providers preferably make their certified Wallet Solutions available for installation via the official app store of the relevant operating system (e.g., Android, iOS). This allows the operating system of the device to perform relevant checks regarding the authenticity of the app.

Of course the chances of any important business implementing a side channel option is effectively zero. Maybe some government agencies will offer the option though.
