Of course it's not the same for everyone. The way I see it, though, the goal is to make diagnosis obsolete. As science marches on, we won't have more categories. We'll blur the lines and turn services into something similar to...
Oh, similar to the way vision is treated, I guess. We don't bother to classify visual impairment as high-functioning or low-functioning. When it matters (for determining what kind of glasses to get, if any, and what adaptations to make to life or school, if any), it's measured precisely, and not just in terms of how impaired you are. (Because someone who's very farsighted might be as impaired as I am, but we couldn't wear the same glasses.) And then with that information, you choose how to deal with it. Do you get glasses? When do you wear them? What color, what material, do you want an ARC? Do you want prisms, or will you just suffer through having double vision? (There's never been any shame for me in choosing that last one. People even think it's cool when I show them my lazy eye. Why can't they react to my stims the same way?) But when it comes to how people react, they don't need labels; a simple "I'm nearsighted" would suffice if for some reason my glasses didn't. If anyone who knew me even in passing found me without my glasses and struggling, all I'd have to say is "no, I don't wear contacts" and they'd understand if I couldn't see something... but they'd know I'm not totally blind, and would probably not be so idiotic as to assume I'd act exactly like everyone else out there who's nearsighted.
