I think there are significant negative side effects to that idea. Players fairly often place buildings in the fog of war.Intuitely I always liked the idea of simply not being able to place buildings in the fog of war at all but only within a players line of sight. I haven’t really thought through the potential negative side effects, but at least that would be a very simple solution from game mechanics perspective that is very understandable
1. Ranged repair issue
2. Flank formation issue
3. Building placement scan issue

The collective pain of a kick in the nuts spread out over a 2 hour game, enjoy!
Perhaps a system like this could be implemented in the future in something like OpenAge, but I doubt a change is possible right now.
Unlike the other issues, this issue does not change or affect the game simulation. Although some players can gain an advantage from doing this, it's not trivial for the many reasons mentioned in the quote earlier. For example, the time and attention diverted by scanning could have been used to flank split xbows away from a mangonel shot elsewhere.
