Because the available date update to the CourseOverview happens inside a view's signal and we have atomic requests on, the read that was happening inside the task happened *before* the write was commited to the database. To avoid the unknown bugs that would come from disabling atomic transactions for that view (since it's large), this passes the date we want down through the signals and tasks so we can skip the DB read at the end.
