[GitHub] [airflow] josh-fell opened a new issue #16635: Update `airflow.models.baseoperator.chain()` function to support XComArgs

josh-fell opened a new issue #16635:
URL: https://github.com/apache/airflow/issues/16635


   
   **Description**
   The `airflow.models.baseoperator.chain()` is a very useful and convenient way to add sequential task dependencies in DAGs but the function only supports tasks of a `BaseOperator` type.
   
   **Use case / motivation**
   Users who create tasks via the `@task` decorator will not be able to use the `chain()` function to apply sequential dependencies that do not share an `XComArg` implicit dependency.  They will need to continue with bitshift notation if there is no implicit dependency using an operator's `.output` property.
   
   **Are you willing to submit a PR?**
   Absolutely. 🚀

   @vikramkoka I've already started working on this and have a PR open but to close the loop, would you mind assigning me to this issue? Unless it makes no difference at this point.  Thanks!
