Matthew Panzarino:
Apple is normally very protective of its private APIs, and rejects apps regularly for using even inconspicuous hooks from it. In this case, it is giving explicit permission to developers to dip into its private frameworks in order to enact a quick fix for this problem through the verification of certificates.
Good to know for developers using in-app purchase.
