   > it can be represented as Jinja template
   
   I do not agree on this. Why do we need to stick to Jinja templates? Seems we are trying to fit the new solution to the existing workaround, when we should think of this as a more generic solution. I dont see why we need a `ArgBase` class. Could you illustrate with an example?
   
   > Should "normal" operators be also XComArgs?
   
   No let's use https://github.com/apache/airflow/issues/8055 instead:
   
   ```python
   with DAG("example"):
       op1 = CreateClusterOperator("op", ...)
       op2 = RunJobOperator("op2", cluster_name=op1.output)
   
   # Or with custom XCom key
   
   with DAG("example"):
       op1 = CreateClusterOperator("op", ...)
       op2 = RunJobOperator("op2", cluster_name=op1.output["cluster_id"])
   ```
