Review Comment:
   The 
[docs](https://airflow.apache.org/docs/apache-airflow/stable/authoring-and-scheduling/deferring.html#triggering-deferral-from-task-start)
 mentions this limitation as `trigger_kwargs: Keyword arguments to pass to the 
trigger_cls when it’s initialized. Note that all the arguments need to be 
serializable by Airflow. It’s the main limitation of this feature.` 
   If we don't need it, maybe then just  avoid passing it?
