 If your app already has a complex view controller hierarchy, it is perfectly fine to have all of them subclass `ASViewController`. That is to say, even if you don't use `ASViewController`'s designated initializer `initiWithNode:`, and only use the `ASViewController` in the manner of a traditional `UIVieWController`, this will give you the additional node support if you choose to adopt it in different areas your application.
