No, not at all.  Just because a security mechanism can be bypassed by
an expert does not imply that it is totally useless.  Security is
still improved overall by being able to catch stupid attackers!

That is certainly a worthwhile goal.  However, there is a valid
engineering trade-off between the value of a system and the cost of
implementing more advanced security services.
