If only symlinks worked for every software / OS. On Windows at least, there are so many different way to link things (including "subst") that it's hard to get idea which one to use. (I do love symlinks, but having spent most of my time on Windows, there are some edge cases I've hit, for example some third_party software not following the symlink and simply failing to open the file..., and no that was not the old .lnk style link)
