Any response is better than nothing and it is sad that is the line to be above. But I know I appreciate letters actually explaining why I was declined, if they are informative it can actually be helpful for me to improve. Especially if there is an assignment with the interviews I really think that feedback should be required. I spent about a week on an assignment like this with 3 interviews and just got back a "nope, sorry". And it wasn't even from anyone I had interviewed with, just the original recruiter.
