If the classic version is abandoned by the authors, the authors doesn't even bother to reply when given all information in order to fix the issue then I very well understand why Cosmos does this... it's because he can. He could just as well sit on the fixes and enjoy them himself but he choose to share them and if a users decide to use his work then apart from enjoying it they should understand that there might be compability issues now or down the road. No more no less.
I would like to see this distributed as a patch for the original file though.
