Okay, so your tar is defective[0], and? I can do that too:

  $ list '#! /bin/sh' 'echo "tar: invalid command" >&2' 'exit 64' >/tmp/tar
  $ chmod a+x /tmp/tar
  $ PATH="/tmp:$PATH"
  $
  $ tar -cf a.tar a/
  tar: invalid command
  $
0: any program that doesn't support --help is defective, which was rather my point.

Fair enough. My point was that there's a category of operating systems where long options (including --help) isn't really a thing. You may of course consider them defective, though I'm not sure everybody agrees.
