I believe you will have trouble finding a unixy system younger than a
decade that allows hard links _from_ directories; they were a nice way
to seriously screw a file system once (so I have been told).  So no,
nobody going for portability should expect that to work.

Did you maybe mean that
  mkdir foo
  touch bar
  ln bar foo
also would not work (untested)?
