I think it should work, because `LanItems.Commit` call commit to `NetworkInterfaces.Commit` here https://github.com/yast/yast-network/blob/master/src/modules/LanItems.rb#L2110 so in the end Items in Network interfaces is correct and you need to only write it. So LanItems Cache is propagated to NetworkInterfaces cache if I understand code in `LanItems.Commit` method
