Hello everyone, The listener plugin API - https://airflow.apache.org/docs/apache-airflow/stable/administration-and-deployment/listeners.html has been in Airflow as experminetal since 2.3, and there have been some changes, but the feature overall has been stable and relatively unchanged since 2.7.
I propose to make it non-experimental, with exception of dataset listener (yet) that were added more recently. Thanks, Maciej
