You may discount the entirety of positives, but there are, in fact, positives. This does in no way minimize the severe cases, rather simply contends ASD is not always negative, which was your original concern.

I cannot agree with your perspective comparison. Vision many help someone learn piano more quickly at first, but is immaterial to their maximum ability as a pianist. A better comparison is early detection of the development of additional fingers or exceptionally large hands (example: Rachmaninoff), both of which directly and permanently affect a person's ability to play difficult piano pieces. This too would be a concerning eugenics issue.
