I'm reluctant to contradict the one serious
attempt to standardize tar simply because gtar
ignored that effort.

I would rather just disable the -l option entirely;
that way, people would get an error message instead
of having the tar program behave unexpectedly.

Would you be happier with this behavior?

   $ tar -cl /foo
   Error: -l is ambiguous
     If you want GNU tar -l, use --one-file-system instead.
     If you want POSIX tar -l, use --link-warn instead.
