My point with the total "no" and comparison to rocket science was based on the insufficient information in the question. One can imagine anything one wants for "allowances" and anything one wants for "special needs" so as a general question, it's useless. It only becomes interesting if one applies it personally.

I do not think my T should make any allowances for my special needs. However, I also do not think my needs are special and I cannot conceive how, in an ongoing conversation, one makes allowances for anything. Therapy, for me, is largely a learning situation. If I were a child in an actual school and it was found I was dyslexic, say, then allowance would not be made for me, instead I would be taught based on how I could best learn.

But the analogy breaks down for me with comparisons to others that has to come with identifying something as being a special need, as if my needs are not like other needs. In therapy, it's one-on-one so there is no other and I cannot be more special than myself. It is like asking the teacher of dyslexics if one dyslexic should be taught differently from another. All else being relatively equal (they are "only" dyslexic) then I don't see a problem.
