Like I said, no one is castigating you for making the request. It's been your
attitude afterwards that is the problem. You've been pointed to the productive
things you can do to resolve the issue that you have:

  1. Submit a bug report.
  2. Submit a patch.

Nothing is going to happen until you do one of these two things. Being more rude
(and yes, you are being incredibly rude and insulting) won't move things along.
