> 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.
