I don't see this being adhered to seriously.  E.g.:

  commit 08a713e078f03e7a870b0111960c6f4c54357152
  Author: Paul Eggert <address@hidden>

      open, openat: document nonstandard FreeBSD, NetBSD O_NOFOLLOW errno

      * doc/posix-functions/open.texi (open):
      * doc/posix-functions/openat.texi (openat):
      Document that these functions do not set errno to ELOOP when
      a symlink is opened with O_NOFOLLOW.

and similarly in Git's Git repo.

(Btw, I think the above is a pretty good summary line.)
