I can testify from personal experience that SunOS 3/4 was in the
latter category.  After creating a hard-link to a directory, things
like fsck and the filesystem dump backup utility got very upset and
confused.  IIRC the only way to recover was to nuke the involved
inodes then let fsck try to pick up the pieces and put them in the
lost+found. IIRC, I managed to recover without losing any files, but
it wasn't a fun day.
