I'm not really sure it's such a strict rule. I would have to do some more research on when was the last time the stones were added to the map, but a three-stone feature was certainly added in one of the patches - you don't have it on the map in 1.00 unpatched version, so maybe these changes are still possible.
I believe the stones are placed not by modifying the map, but by reading the locations from strait.csv. As such, it's not strictly speaking a map modification.
And as I said before, the change could be made without any graphical change. There's no graphical cue that the Jylland-Sjaelland-Skane straits exist, and we have them. Why not have another invisible strait here? I don't think anyone can really argue with it from a realism perspective.
Here's a
satellite image of SW Japan that clearly shows the seperation of the islands, and the tiny size of the area where the strait is narrow. It's more clear in the high-resolution versions that are linked on that page.
This page contains several pictures of the bridge that crosses the strait at the narrowest point. That bridge has a main span of 712 meters, making it one of the longer suspension bridges in the world. Again, that's equivalent to the Bosporus.
Again, factually the existance of a strait here is beyond debate. Given that there are other places in the game where "undocumented" straits exist, I see no reason to not have one here.
