Then you can’t use left-pad, because it doesn’t support that and you don’t maintain it. So you make your own module to suit your needs, which is a very good thing and returns somewhat to the actual point, which is that anyone can make their own left-pad that matches the existing module, so the author’s wishes wouldn’t have a huge impact even if they were that the module stayed down, which they weren’t. Phew!
