Application module exposes events (e.g. onLaunch, onResume) from which there is no access to useful parameters. For example, in iOS app when application:didFinishLaunchingWithOptions: is called the TNSAppDelegate calls application.onLaunch() without parameters. In application.onLaunch() there is no way to access lunchOptions argument of application:didFinishLaunchingWithOptions: method.

This behaviour is needed to support Facebook iOS SDK with application module. Facebook iOS SDK requires to edit App Delegate: https://developers.facebook.com/docs/ios/getting-started#startcoding.
