Coding this won't be easy. Nothing really is. The littlest things can have big repercussions where you never expected them. That doesn't mean changes won't be made, but it does mean it needs to be functional to the game and deemed worthwhile. While any 'improvement' may SEEM worthwhile, especially to those who proposed it, it's the time and effort needed to code and test it that determines whether it really is. The to-do list for this game (and WinSPMBT) is always full and time is always short. So only things that are considered to have an added-value (as opposed to appealing to the esthetics of a handful of players) get on the list. And even then it can take a very long time before it gets realised (for the old-timers, reverse movement and barbed wire!!!).
So it's a choice on where the (precious) time will be spend.
And the designers have to like it off course.
