Review comment:
Actually I also do not like the way of tuple.
But we provide the method of `createShuffleIOOwnerMetricGroup` in factory,
and it is only used for adding group simple. So it might bring confused that
which `addGroup` should be done inside factory and which should be done
outside. The scope/rule seems not clear.
