[GitHub] [airflow] casassg opened a new issue #8054: [AIP-31] Add dependency relationship on operator when templated_field is XComArg

casassg opened a new issue #8054: [AIP-31] Add dependency relationship on operator when templated_field is XComArg
URL: https://github.com/apache/airflow/issues/8054
 
 
   
   **Description**
   
   XComArg allow us to set explicit XCom messages between operators. Adding a dependency between Operators is needed as it does not make sense to execute an operator that requires an XCom from another operator. 
   
   **Use case / motivation**
   
   As a DAG Author, I want Airflow to automatically detect that an operator that I initialize using an XComArg is set as a downstream dependency from the XCom origin operator.
