`reloadData()` implementations are set to private on `reloadProviderData()` All calls of `forceReload()` or `reloadData()` target `QgsDataProvider::reloadData()` what calls the implemented `reloadProviderData()` of the provider and `dataChanged()` signal is called allways. That this signal is called changes the behavior of the `dataReload()` calls of all providers.
