> The main argument in favor of treating it as a single condition tends to come from the advocacy side, rather than from the diagnostic side.
Seeing it as one single conditions is established scientific consensus not some advocacy thing.
The diagnosis "Asperger's" was invented by Hans Asperger, a Nazi scientist that was responsible for the murder of many autistic children. It was never about science. It was invented because he thought that some autistic children might have a potential to become scientist and the like and therefore useful to Nazi Germany and some might not.
Hans Asperger decided which autistic children should be murdered and which one to be spared purely based on ideology.
Autism is something you are born with but support needs can change over your life depending on many factors like you environment, if you are diagnosed early and so on. They are not fixed.

No, it wasn't. The diagnosis of “autistic psychopathy”, which loosely corresponds to much of the range of the modern diagnosis of autism spectrum disorder was invented by Hans Asperger (Asperger does not seem to be the first to have described the condition, though he invented that name; a Societ doctor seems to have recognized a similar condition a couple decades earlier.) The distinct separate diagnoses of “Asperger’s syndrome” was invented later (the term seems to have first been used in 1976), and roughly corresponded to the “higher-functioning” individuals within his diagnosis of “autistic psychopathy” that Asperger described as potentially socially useful.
