I think that the point is just to be able to talk about the thing that people mean when they talk about somebody being narcissistic, which generally is not the clinical diagnosis.
It usually means that the person doesn't like the person they call narcissistic. If Alice calls Bob narcissistic that might tell you more about Alice then it tell you about Bob.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
