> With FLINK-8749, we introduced that a {{ConjunctFutures}} cancels all of its
> input futures if it is cancelled. This has, however, some unpleasant side
> effects since a all of the cancelled future's completing callbacks won't be
> called. Since this can lead to subtle bugs like in FLINK-9908, I would
> propose to remove this feature and require the user to do the cancellation of
> input futures explicitly.
