I also hate this. In asking the question, I frequently have to boil done what can be a very lengthy set of requirements and constraints and so on into a compact minimal version to demonstrate that I want to know how to use Y to X. But then comes the 'why you doing it that way', and the answer is because I have a lengthy set of requirements and constraints that I don't want to have delve into because all I want to know is how to use Y to get X. Frustration!
