I don't know. I seem to have more serious sensory issues and with routine than most people on the internet who identify as being on the autism spectrum. It causes issues. But social issues, no. I used to have them as a small child, didn't know how to approach other children for a brief period of time, played alone. I had a hard time understanding feelings as a child too. Now I don't think other people can tell, especially when they know me superficially. I don't have to control myself much to socialise. I'm not considered odd. Learning - I'm a very good learner and stand out academically. So "primarily social features", no, it doesn't apply to me. I don't know what to mark, light or moderate.
