### Description Instead of using `list` for holding the tags of a specific dag (as we can see at the [docs](https://airflow.apache.org/docs/apache-airflow/stable/_api/airflow/models/dag/index.html#airflow.models.dag.DAG)), I suggest using `set` instead, specifically [`MutableSet` for the type hinting](https://docs.python.org/3/library/collections.abc.html#collections.abc.MutableSet), and [python `set`](https://docs.python.org/3/tutorial/datastructures.html#sets) as the default implementation. ### Use case/motivation I would want to add multiple tags (even the same ones) faster, without worrying about duplicates, and reduce the memory usage because of it. ### Related issues _No response_ ### Are you willing to submit a PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
