I think technically, Include What You Use would necessitate including
owner_settings_service.h too. You are depending on a fully-defined type by
invoking a method of this class, and there is no reason to assume that the
factory's header provides such a fully-defined type.

But I'm not using OwnerSettingsService class in this translation unit.
OwnerSettingsServiceFactory::GetInstance() returns an instance of an
OwnerSettingsServiceFactory, not OwnerSettingsService.
