Dunno, it doesn't need to do anything, vanilla-compatible maps are fine as they are now. Gameplay mods are normally intended to run in any map interchangeably. That some of them allow you to fly or throw black holes, eh, it's up to the player to skip a map. And besides the maps are being generated to play them, so the skipping maps thing is like buying a coffee and throwing it down the drain, you can do it but why.
I just happen to hate invisible walls, they obliterate immersion.
