Complained on override_settings(INSTALLED_APPS=...).

Browse Source 
Currently such overrides aren't reflected in the app cache.

It would  be possible to handle them. But that doesn't look like a very
good API. It makes it complicated to express "add this app" and "remove
this app", which are the most common operations on INSTALLED_APPS.
