Resolution: Won't Do
Not a must at the moment so close it for now.

> {{SchedulingStrategy}} requires partition consumable notification to make
> scheduling decisions.
> According to {{SchedulingStrategy#onPartitionConsumable}} definition, all
> partition consumable events should be notified to {{SchedulingStrategy}},
> including those from TMs (pipelined partitions consumable for data produced)
> and from within JM(blocking partitions consumable for producer finished).
> In this way, the LazyFromSourcesSchedulingStrategy does not need to maintain
> the result partition status by itself. InputDependencyConstraintChecker can
> be simplified a lot in this way.
> Besides that, LazyFromSourcesSchedulingStrategy does not need to be aware of
> result partition types(PIPELINED/BLOCKING) in this way.
> It would also simplify the input checking for pipelined region scheduling.
> More details see
> [here|https://github.com/apache/flink/pull/9663#discussion_r326540913].
