@laudatoryLunch I’ll repeat my earlier reply regarding Splash Damage’s stand-point on it. 
Basically - it’s fine to use, because it’s a planned feature for the point. Don’t get me wrong though, I understand your point of view too, and I do agree third-party modifiers to the game shouldn’t be allowed…
But then, some people take it too far - such as the folks who say altering colours in the game for colourblind people gives them an “advantage”. Which is, as I’m sure you can agree, complete nonsense.
It’s just knowing where to draw the line, because for most people it’s a very subjective matter, due to varying opinions and degrees of scale. Right now though, considering the devs themselves have given this one the green-light, I think it’s safe to say it’s fine.
