If you ask the majority of people if somebody who they do not perceive as engaging in autisitic behaviours, and was not diagnosed as autistic, but considers themselves autistic, is autistic, they will say no. Scientifically (which how it’s defined in the OP), it’s not defined by psychiatrist appraisal and self-assessment plays no necessary role in the process and alone holds no diagnostic validity. We can also invert this: self-denial doesn’t make one non-autistic if they’re seen as engaging in autistic behaviours and are diagnosed as autistic by a professional.
I’ll concede that a minority believe that autism is self-definable though. I’d prefer things that way myself, but the among other things it would make it impossible to gatekeep services for the autistic if self-diagnosis were held in the same esteem as physician diagnosis, so it won’t catch on anytime soon.
I’m not sure what point you are making with this reply. I’m late/adult self-identifying autistic. I’ve done this with some of the standard tests that psychiatrists use, attended workgroups related to the topic, and studied extensively. Self-diagnosis is highly accurate for autism, both for positive and negative evaluations.
I am also pursuing a formal diagnosis because so many people downplay it when I tell them I’m autistic. I don’t have the affect at first glance, but it does come out in my behaviors if you get to know me a bit. I’ve also had the luxury of therapy, eduction, etc.
I also agree that the categorization is overly broad and your original post resonates. There are various non-overlapping clusters of traits that fall under autism.
I do think, however, that at the core of it is a common difference in information and sensory processing.
Adults that get diagnosed later typically have developed very good ability to mask so casual acquaintances probably don’t suspect they are autistic. So it’s not surprising they would downplay it.

I've also gone into autism communities before and declared that I had self-undiagnosed myself with autism, which is something I've desired recently, to re-diagnose myself as not being autistic and either having nothing or ADHD. This was totally rejected, and repeatedly brought up was my admittance to a lengthy period of diagnosis, overseen my multiple doctors, from a very young age, which all were seen as evidence of the validity of my diagnosis (conversely, I'd presume, they treat the opposite as more less valid or invalid). Interestingly the same people generally accepted diagnosis, but to reject a diagnosis, well that was beyond the pale and denialism. I brought up the same to a psychiatrist, saying I wanted to be treated by a psychiatrist for ADHD and NOT autism because I believe it will lead to superior outcomes. They blew me off, exasperated, saying that any psychiatrist would simply observe my symptoms and deem me autistic and treat me that way no matter what I did, denying that I even had the capability or possibility to receive treatment which was not based on the premise that I was autistic. Metabolic testing and self-diagnosis be damned.
Just this moment I'm in the process of seeking accommodations. I self reported autistic symptoms to my employer. In the past, during interviews they have accepted my diagnosis and pledged to "accommodate" me accordingly, and I was ticked off as a diversity hire. They asked me to verify such symptoms with a doctor. They subsequently said they reserve the right to an independent psychological assessment of myself or my records. This is very pleasing to me, as either I shall receive accommodations and an affirmation that I am autistic, or my undiagnosis, which is truly a win-win.
If I was in family court, and it was argued that I was unable to say take care of children because I'm autistic, I could not successfully object on the grounds that "I'm not autistic".
Yet my observation is what is considered the true measure of somebodies autisticness, the validity of their diagnosis and their symptoms, is independent psychological assessments by an examiner not beholden to your own self-assessment. I theorise this is both because of a lack of faith in the competence of either of us to assess an autism diagnosis, as well as a lack of faith in our objectivity. I've met a number of self-diagnosed people who are shy about disclosure or asking for accommodation BECAUSE they are self-diagnosed, and while obviously believing in the reality of their autism, are either self-sceptical or believe in others scepticism to a degree not commonly seen in those medically diagnosed.
I don't mean to be exclusionary or gatekeeping, just descriptive of what I believe to be social/political/legal/scientific reality. I don't like that things are this way, I'm aware that hilariously I've never seen ANY evidence that suggests physician diagnosis is more accurate than self-diagnosis, I'm aware of the many historical problems with physician diagnosis, I merely believe that they ARE this way.
I’ve never met anyone that self identifies as autistic that didn’t have some obvious behaviors (in the tech world there are a lot). This seems like a strawman.
I’ll concede that a minority believe that autism is self-definable though. I’d prefer things that way myself, but the among other things it would make it impossible to gatekeep services for the autistic if self-diagnosis were held in the same esteem as physician diagnosis, so it won’t catch on anytime soon.
