The iOS notification system was originally used only for phone calls and SMS. Things you would want to interrupt the user for in most cases. It hasn't scaled well with push/local notifications. I was disappointed they didn't address this in iOS 4 but at the same time I would rather they get it right so the end user experience can be consistent until iOS9 when it has to be reworked again to scale. I generally don't mind that Apple takes their time to get things right since the payoff is usually worth the wait.
