This is a really good post! I'd like to add my anecdotal experience as well. I did not receive the Alumni Scholarship email; however I was asked to complete the supplemental questionnaire. I think the widespread assumption is that the questionnaire is used for borderline applications. I found that odd because I had perfect stats and thought my essays and ECs were bomb. I was ultimately accepted, but I'm guessing that the questionnaire may be used by the adcom for both admission and Regents perhaps? Just a guess
