      Based on fleet statistics the number of chunk migrations is minimal. The shard filter is a correctness security mechanism to filter out all chunks that do not belong to the current instance as it has ben migrated. As the actual filtering is very seldom the decision here is to ignore the shard filters during costing respectively define the cost as 0.
