At the moment, if you send 1 Peasant and 1 Kuafu to gather gold, it is shown as 2 units gathering gold. With this feature, it would be shown as 4 units (since the Kuafu is worth 3 population). Gathering gold with 2 Atlantean citizens would also be 4 instead of 2 (since they are worth 2 population each).
By default, it’s easy to multiply Atlantean citizens in your head if needed; but with the Chinese it’s harder to keep track of the economic state by just looking at the villager counter (having 5 Peasants on a resource is not the same as having 5 Kuafus).
Having this feature as an option would be well appreciated.
