Review comment:
There is a design pattern in several operators that include the option,
rather than a forced action, to wait for termination/completion if desired.
https://github.com/apache/airflow/blob/main/airflow/providers/microsoft/azure/operators/data_factory.py
https://github.com/apache/airflow/blob/main/airflow/providers/google/cloud/operators/dataflow.py
https://github.com/apache/airflow/blob/main/airflow/providers/google/cloud/operators/dataproc.py
https://github.com/apache/airflow/blob/main/airflow/providers/tableau/operators/tableau_refresh_workbook.py
This way users could choose whether to wait for the task to complete as part
of the operator or use a sensor to poke for status (mainly useful for
long-running actions). Of course, Deferrable Operators solve for this too 🙂
