I'm of the opinion that Minthara deserves Origin status. Although admittedly I also haven't done much of a playthrough with her either (I am working on it though and have her saved on 1 play in Act 2 atm but that was going the neutral route), I think having to knock her out should be able to do just that, knock it out and not "kill her", So I am of the opinion that while this game is pretty fun and good, It could be a hell of a lot better and polished. BG3 feels like a small world Linear if you will. So hopefully down the road a lot of "things" change.
