Airflow 2.6.0 introduced a new Notifiers framework. I don't want to increase the complexity of the project too much (or force users to sign up for an SMTP email service), but a lot of the value of this system comes from not having to closely monitor it, so notifications are a valuable feature. So implement a [notifier]((https://airflow.apache.org/docs/apache-airflow/stable/howto/notifications.html) and figure out a delivery mechanism.
