API/framework App?

Apple's Site has recently had a new post saying that it needs a Framework QA Engineer to develope the very first app to use it's own framework for the next iOS
It's nothing new that Apple plans on adding a framework to a new iOS, but what makes this really interesting is that the new framework is specifically for the app!

The Exact Job Description is Right Here:

“The iOS team is looking for a software engineer with strong development and QA skills to help us ensure the iOS SDK is able to meet the needs of hundreds of thousands of developers producing the next great iPhone and iPad apps.
Responsibilities in this position will include developing and maintaing a set of iOS test apps for new and exiting APIs that are released in the public iOS SDK. A significant amount of time will be spent working on feature bring-up for new APIs released to developers. This includes developing the very first app to support new APIs/frameworks in the iOS SDK and also developing some of the accompanying web services, tools and test data sets needed to ensure the features works end-to-end for developers. You will also need to work in collaboration with different engineering teams within iOS and Apple in order to ensure the quality of the APIs/frameworks meet our standards.”

 From the description it suggests it could be completely compatible with third-party applications.
Yes, User-Installed(AppStore) applications.
A simple PassBook-like App Plausibly.

From Apple's Background, the API/Framework Might be a rather BIG difference.
If it Follows the Previous Pattern-like sequence of "Apple".
