Understood. I'd argue that the need for additional classifications is fairly evident just from the comments in this thread. Saying someone has 'autism' doesn't tell you much in terms of what level of care they may need - those who fall into the neurodiverse crowd may require no care and perhaps minimal supports, while some require lifelong care. The burden on families and society is quite different for these groups, and further classifications are necessary. There are also several related health patterns (digestive, allergy, etc.) with many who are usually more severely impacted which will likely lead to more research on causes. Some advocate for an additional medical diagnosis instead of just referring to the neurological. Down the road there could be a separate diagnosis for those.
