Kurt Young commented on FLINK-16485:
------------------------------------
It's not only about the legacy planner, but also it might introduce new changes
or maybe new features to DataSet API. I'm not sure whether there will be enough
community capacity for changes related to DataSet API.
I'm not saying we shouldn't do this feature, just sharing some concerns.
