I can tell you no, because it isn’t done.
Canned responses are actually a huge step forward for google. The normal thing is complete silence. Canned responses seem to be selective as of yet, too. Most receive nothing.
Action taken – yes, many times the reported group of sites (never one but networks of blackhat sites) have disappeared within a week (sometimes two) of my reporting. None of these reports got even a canned response, but action was taken.
Feedback – generally not happening. You can get feedback if you report through the google webmaster tools, but it is extremely rare.
