I'm going to be honest this doesn't really make sense seeming there's a in-game map editor. Thus meaning, it's also for making maps.
You didn't get the point.
I'm saying the games purpose ISN'T to make maps, but they still have the feature.
The games purpose also isn't to cheat, but they still have ways to make cheats work.
In all honesty, regarding singe player I can do whatever I want with it.
