This is one of the main issues, I think. The wrong questions are being asked. Studies focus on quantitative data and throw a survey or simple task at the subjects and don't record very meaningful results/responses.
But, also, imagination in this sense, I have been told, does not mean the type that you have described. It is more about the ability to read between the lines and to "imagine" what another person means, thinks or feels. Sort of like ToM. When someone asks "What did you get up to over the weekend?", if you have good imagination then you understand that they don't want you to describe every detail of every single thing that you did, but just comment on the interesting stuff. If someone asks a vague question, you use your imagination to understand what they meant or want.
(This doesn't mean I agree that people on the spectrum lack imagination.)
