I wish Data Protection (https://developer.apple.com/documentation/uikit/protecting_the_user_s_privacy/encrypting_your_app_s_files https://developer.apple.com/documentation/uikit/protecting_t...) would allow app developers to use a locally-derived key to secure app data. Then, even in iCloud Backups, you'd still not have the key to decrypt specific app data without having unlocked the device. I realize you could do this right now (in theory) with your own encryption solution and Keychain, but a first party solution that's as easy use as the Data Protection features/apis would be really nice. Apple has plenty of data that I wish was E2E encrypted, but if many/most of my 3rd party apps had their own data locked, that would go a long way in the right direction.
