> If we ever want to add edge information beyond just a label (e.g. add a longer description), it means we have to go back to this pattern Can you give an example of a long description that has to use `Label` but not otherwise? How about `task1 >> "this is a label" | task2`? This is the exact opposite of the Beam Python SDK [example here](https://beam.apache.org/documentation/sdks/python-streaming/). Though I am a bit hesitant to introduce another special operator for Airflow, I think it's still better to introduce a `Label` inheriting from `TaskMixin` for these 2 reasons: - Conceptually, label and task should not be treated the same. The label is metadata but the task is a task. They are different in both UI and execution. - In general, I don't like the *explicit* import of UI components in DAG code. I think DAG code should focus on execution/dependency logic -- This is an automated message from the Apache Git Service.
