in natural human interaction you can set the goal to work towards a fantastic friendship or a blossoming relationship - two very different tracks of progress. *Sometimes* it can get messy or blur the lines.
In BG3 I feel like every kind answer is working towards a relationship as the end goal, further accented by a linear single approval bar.
I don't think I care enough about this aspect to have a strong opinion, but is what I've noticed in my playthroughs.
