A part of all psychology diagnoses is that it must both match a definition and negatively impact someone's life. So if you never had to care about what neurotypical people think, then it wouldn't rise to the level of a problem and there's no diagnosis.

You see people care about this stuff because they go to their therapist and say, "boy there are a lot of neurotypical people I have to predict, and being slightly better at reading autistic people doesn't make up for it."
