Hi guys. Starting from upcoming cordova release (6.0.0) we have PlatformApi implemented and used by three major platforms (Android, iOS and Windows). This means that we now have a lot of code in cordova-lib which exists there only for maintaining compatibility with previous platforms versions. I'd love to remove this duplicates from lib, but this means that we'll lose the support for previous platforms in newer cli, and hence we'd need to deprecate this support first.
So I propose to add a deprecation message about removing support for old platforms into upcoming cordova@6.0.0 and remove this support totally in next major cordova version (7.0.0). The message will be emitted each time when polyfill is instantiated for these platforms instead of platform's Api class and might look like this: "The support for old platforms via PlatformApi polyfill is deprecated and will be removed in next versions of cordova. Consider upgrading your platform to cordova-android@5.0.0 or newer." - Best regards, Vladimir.
