You appear to presume that to be useful a technology must solve all known

No but new technology must actually solve more problems that it creates. Car locks
that are easy to break cause little harm apart from this fact.

If your network doesn't require that extra level, there is no need to deploy
it. At the same time, there are network managers that insist on having that
capability.


I believe that the lessons learned from the types of attacks prevalent today will bring
about a change in the types of solutions network managers ask for.
