Hmm...  Wow.  I decided to check HP-UX 11.11, a now rather old release
from twelve years ago in 2000, the oldest easily available to me, and
got this:

  $ /usr/bin/rm -rf .
  rm: cannot remove .. or .

So I guess GNU coreutils is in good company with traditional Unix
systems!  It has definitely been that way for a long time.
