Do you have a link? I'd love to look at that and see how much they responded to WotC's feedback. And what feedback was left.
I saw it a few weeks ago on the official swordcoast.com forums from a user named "Mad.Hatter" who outlined which game files contained what data, and what it meant for the game's future updates and mod-ability. I skimmed the first few pages of the General Discussion forum and didn't see the thread anymore, but I did see a few people discussing it in other threads. Wish I could be more helpful than that, but hopefully that's enough for you to find what you're looking for.
