It's not only that, it also supports sockets and pipes that you can access via /proc/pid/fd and not via a real symlink which would try to open eg "pipe:[23456]" instead of the real file. So you can't get rid of it without breaking existing apps (starting with your shell for which /dev/stdin is a link to /proc/self/fd/0 for example).
