So, i remember back in the day when @jamalex commented on code style all the time for me.  At the beginning, i think it's useful, to get on the same page.

Please indent things like this as:
```

        call_command_async(
            'languagepackdownload',
            manage_py_dir=settings.PROJECT_PATH,
            language=data['lang'],
        ) # TODO: migrate to force_job once it can accept command_args
```
Yes, even including that trailing comma.
