Note that for each skipped topic, an empty workunit is created for each partition to preserve its checkpoints.
In single-level bin packing mode, it still assigns all partitions of a skipped topic to the same workunit / task,
so that a single empty task will be created for this topic, instead of one empty task per partition.
