Yes, I also think something will be added later in development. But I am worried the developers might not take it far enough. I want my companions not simply disagreeing. I want them to leave or even turn on me if they think I crossed the line.
For example, if my character kills anything she meets, slaughtering entire cities, it'd take a very special kind of personality to continue travelling with her. No sane person would want to help a murdering psychopath without a very serious reason. And escaping Fort Joy is not such a reason.
Or if my character suddenly attacks a friend of my companion, said companion shouldn't happily drow his weapon to help me. Instead he should attack me to save his friend.
While I'm sure some interactions will be added later in development, I'm not so sure Larian will add something like what I described above.
