 Since 1.7, whatever can be done in a `class_prepared` listener is probably
 better done by inspecting the app registry in `AppConfig.ready()`.

 As the documentation notes, reacting to `class_prepared` is impractical
 because the app-loading and meta-refactor APIs don't work yet.

 Even if we keep the signal — I once tried to refactor this area and it
 [https://code.djangoproject.com/ticket/21719#comment:13 went downhill
 quickly] — I think we should remove it from the public API.
