I just registered to ask the developers about this, I haven't got a reply yet, but now I see why.
It would be good to release it to the community, as they could translate it, and maybe make a server for their country, and if someone comes up with a new idea and can code it into the game, then all the servers could share the same features.
BTW I would personally make a farming addition, so you can grow crops and all, AND make a superb banning script: If you kill someone in a protected town you'll get banned for 1 week, and if you kill a guard you'll get banned for 1 hour. Maybe delete one of your random items on your character...etc
