Invisible to whom?. The reason the AI is given the knowledge is to make pathing a bit easier and less demanding on the CPU. It is at time a benifit to the AI, but it is a double edged sword. Thia due to the ability of humans to use lures like the bare naked lady tactic or empty towns, which you will fill as soon as they approach.
It may be an interesting addition to the game, but I doubt I would spend the shields and time to build it as it would not help me. It may help the AI some as it wil force the human to investigate the town, maybe.
In most cases I do not care what they have in the town, when I attack as I am bringing over whelming force.
The privateer is similar duck, it does not have much impact as the human tends to know who owns it and for me, I don't care as I will sink anyway. The AI attacks them the same way.
I always found the Cover Of Darkness to be a real distraction and not worth making.
