Of course I may be completely off-base here because I don't know anything but the technicals, but I can't think that modding things is going to be healthy for the EA environment. How is Larian going to pull metrics from our game data if it's been modified? They're clearly working on establishing a baseline and tracking what the most popular character creation options are. If the data comes back as incomplete or indecipherable somehow because changes have been made, this is going to do more harm than good during the data collection process.
Don't get me wrong, I'll 100% use this if it's live after official release on Steam, but as of right now it might be harmful to the process.
It's a known issue which is why the modding forums aren't yet open. Stuff like this should be fairly harmless though, IMHO; and while I haven't yet got any official feedback, I suspect it's very likely that the devs/QA people/etc will have considered the likelihood that some people will try to mod the game from day one. So my personal opinion is stuff like this is okay: it's not like anyone is creating major add-ons with scripting and stuff like that.
