its a free open source game so i doubt they would have a problem releasing the patch they probably would be excited about having a modding community around the game
i hope so, may few or many modder player give good feature and not break the game, but it will attract abusive modder.
well take Minecraft the modding community with that game started out as very simple mods such as unlimited items and flying. just look at how it evolved. i personally think a modding community would be very beneficial to this game. also the developers mentioned that they wont have much time to develop the game so a modding community would be able to fill the void of features while they can not. who knows they might even add features that have been community created.
