There already kinda exists a category that is No WW(allows OoB).
In theory its neat to think about a category that would allow all these cool out of bounds tricks, but really the route just becomes one out of bounds jump after d2 that sends you into the nightmare room so none of the tech is really there because the run is only 20 minutes long.
That and the game has a chance of randomly crashing once you enter the nightmare room, which just makes it incredibly not fun to run.
I'm aware of that category, though I'm thinking of something more along the lines of tompa's definition of "no wrong warp". Where you can't transition between cave systems that shouldn't be connected, so you still need to do all the dungeons. Could be interesting.
