uranusjr opened a new pull request, #50760: URL: https://github.com/apache/airflow/pull/50760
Previously, when a dag does not have start_date, 'once' would never run because the scheduler does not know when to do that one run. This was not particularly problematic in Airflow 2 since you almost always are expected to provide an explicit start_date to a dag. In Airflow 3, however, since start_date=None is the implicit default, it is more common for people to forget about the start_date, and be surprised when the dag never runs. After some brief discussion, it's decided that it's more intuitive for this argument combination to run the dag 'as soon as convenient' instead.
