This game is years old, and far past the point of developer support. At this point I don't really think that it matters whether a feature was intentionally designed into the game or not, it will be integral to how people play. So changing that feature will result in a buff, nerf, etc., even if the unit was never intended to perform that way at first.
As long as the units' behaviors moves closer to the way they should, who cares how it is discussed?
