To be fair, there are gradients to it, and what little they dislike can easily be regained by everything they do like. I had Codsworth with me for a long time, and I picked locks, and stole from raiders, and he disliked a few things, but he still ended up adoring me in the end. As long as its not "Codsworth really disliked that". I think it's fine. Then again, it's Bethesda, so it wouldn't surprise me if the "so-and-so didn't like that" thing was completely broken, and their standing with you never actually drops and Codsworth would have actually hated me in reality. Hard to tell
