> After FLINK-19317 and FLINK-19318 we don't need this setting anymore. Using (explicit) processing-time windows and processing-time timers work fine in a program that has {{EventTime}} set as a time characteristic and once we deprecate {{timeWindow()}} there are not other operations that change behaviour depending on the time characteristic so there's no need to ever change from the new default of event-time. Similarly, the {{IngestionTime}} setting can be achieved in the future by providing an ingestion-time {{WatermarkStrategy}}.
