Why do we care ? You have to be the network administrator to set values,
there are cases you may want to be out of the spec and you are
privileged. The kernel does need to stop things being done which are
fatal but running around restricting privileged administrators who have
the ability to bring the network down anyway isn't its job.

Seems bogus extra code to me - stops things working that should be
allowed too.
