Depending on broken behavior is itself, broken behavior.  Every other
unix utility writes its output to /dev/null when asked to.  Tar should
do so when asked as well, rather than silently ignore your instructions
and fundamentally alter its behavior.  At the very least it should print
a warning informing you that it has decided to ignore your instructions
and not do as you asked.

What's next?  rm deciding that you didn't REALLY mean to delete that
file and just pretending it succeeded?  Sheesh!
