There are 1001 things that could have unforseen consequences, when root 
is doing something ;-)

This is getting into the area of standard Linux kernel policy (or lack 
thereof):  let root shoot himself in the foot, if he wishes.

I would certainly -want- to be able to dd -from- my underlying disks,
