This code of conduct seems to follow a trend in that it tries to regulate inter-personal interactions on a microscopic level. I find this somewhat worrisome in that I think it does not benefit a healthy society in which people take responsibility for their own mental well being. Indeed, a code of conduct as this is somewhat insulting as it implies that persons can not look after themselves when they interact with other people.
For personal reasons I have had my fair share of psychotherapy, and one of the more important lessons I learned is that in a robust, equal-leveled relationship people assume responsibility for their own (mental) well being. That is, I am not responsible for your happiness, nor are you responsible for my happiness (assuming a level playing field, obviously). I have learned from experience how a relationship can become lopsided and toxic when the people involved thought otherwise.
There should be some general framework within people should interact, but within that framework people should be able to determine how they do (or do not) deal with each other.
