For a moment get off your freaking high horse, will you? If you cannot help try not to be sarcastic or criticize. I did read it and I have an understanding of the documents required. But I wanted a second opinion from the applicants who have gone this route before. BECAUSE there are usually things that are included in, for example, in a PR application that go over and above what the INS requires. It is called being careful or paranoid. Pick your poision.
So before you get all high and mighty try to understand the rationale behind the question being asked. But that might be asking for too much.
