Yeah, I've thought about it. Haven't merged it in yet, as I'm not completely sure I should. Personally I prefer to play with it on, but lots of people prefer not to. In the end I'm probably going to merge it in, but turn it off by default. It's only python IIRC (as BUG itself), so I should be able to do it while others (or myself) work on the xml.
edit: I'm also kinda hoping that if I delay it a bit, they can get the PLE stuff worked out. It looks like EmperorFool and Ruff_hi will be able to speed up the unit plot list, which should keep the game more playable on older computers in the endgame.
edit2: Hmm, looks like he included BULL, that'd mean dll changes as well... not too sure I'd like that.
