The idea is ECL0, preferably appless subraces. I should've been more clear from the start.
To expand on this a bit, app subraces don't really need a lot of discussion; Since they are controlled by default, they can just be added, no issues. You can ask / apply for them, and if a scripter is in the mood (and the app is good) it can just be created then and there, even (Cansin is one such example).
Appless is what would need considerations, as there wouldn't be any controls, hence this thread.
