Extend UIViewController with the infiniteTabBarController that holds them

Does it make sense to you to provide a built-in way for a VC to know his M13InfiniteTabBarController?
There is a way for the VC to get his infiniteTabBarItem, and iOS provides a way for a VC to get his UITabBarController. Can we add this extension to the library? (And if yes, would you also roll the podspec?)
