> After FLINK-7720 fixed, the two methods of {{Environment#acknowledgeCheckpoint}} have been actually useless, and their usage have been overridden by {{TaskStateManager#reportTaskStateSnapshots}}. 
> More generally, we would consider {{Environment}} interface as getter to access components instead of doing real actions. I prefer to remove {{acknowledgeCheckpoint}} and {{declineCheckpoint}} methods or at least deprecated them.
