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.
There is data to be collected though. I mean, if a significant number of people are using a particular mod, then it tells Larian that what's in game is insufficient, and gives them an idea of what players would prefer to see. Like tieflings not being weirdly limited on hairstyles.
