Well, doesn't that sound like a bug? Does POSIX require all these warnings and
an error return even on successful completion? Why would anyone want a command
that always returns an error?

       --posix
              Be strictly POSIX conformant. Implies --verbose. This option
              currently has no other effect. Posix conformance is assumed if
              the environment variable POSIXLY_CORRECT is set.

It doesn't document it changing the return code, in fact it specifically says
it has no other effect.
