   Isn't there no worker_autoscale option set by default:
   
   ```
   # The maximum and minimum concurrency that will be used when starting workers with the
   # ``airflow celery worker`` command (always keep minimum processes, but grow
   # to maximum if necessary). Note the value should be max_concurrency,min_concurrency
   # Pick these numbers based on resources on worker box and the nature of the task.
   # If autoscale option is available, worker_concurrency will be ignored.
   # http://docs.celeryproject.org/en/latest/reference/celery.bin.worker.html#cmdoption-celery-worker-autoscale
   # Example: worker_autoscale = 16,12
   # worker_autoscale =
   ```
   
   So where is this default coming from?
