Sure but that just means there's more to add to the game if larian was on a crunch to finish the game. Also she isn't the only mindflayer option? Also with the game being so wildly popular it would only make sense for larian to try and make as much of their new fan base as happy as possible to further promote their next release. It only makes sense for karlach to get a happy ending given how wildly varied the games endings already are especially when you factor in dark urge. And yes I'm on industrial grade hopium right now.
