I think you may be right, but that is a technical aspect. I think there is a psychological aspect. Some people want an exclusive space where they are not reminded work people or relatives or high school bullies exist at all. Even if they allowed you to block any mention of those people it might cause even more "drama" if they keep messaging you and you never reply.
