Nah. While growing up as a Weird Kid was hard, I don't really need accommodations as an adult in my thirties. I don't score particularly high on the RAADS (around 65 - 70) or other evaluation tools.
As a kid, I definitely would have scored higher. I couldn't stand wearing socks. I infodumped about birds at every opportunity. I talked like I had eaten a thesaurus. I couldn't switch tasks to save my life. I ate the same food every day (Lipton instant soup) for years. But I scored really high on standardized tests so nobody really saw the need to ask why I was such a strange kid. I lived with my grandparents and spent most of my time around old people who enjoyed my odd mannerisms and willingness to read them the newspaper.
Sure, I still find some textures and sounds gross. I love listening to the same song for two hours in a row. I cannot tell when people are lying to me out of politeness. But I also have a lot more control over my day to day life than I did as a kid. I don't have to wear clothes or do tasks I find uncomfortable. Infodumping is a key part of my job. Many of my friends are neurodivergent and those who aren't understand my quirks.
It wouldn't really change anything about my life if a doctor told me I am or am not autistic, so I don't really see a need for documentation or diagnosis. Sometimes people are also just kind of weird and it doesn't require categorization. Even if I'm not autistic, I believe in their beliefs (clear communication, pursuit of special interests, sensory seeking and sensitivity, etc).
