Is it possible that anyone running an ISP or NSP would be dumb enough
to ever do this? (rhetorical question, I know the real answer.)

While I would not like to see it removed (some where, some time,
someone will have a reason to want this), I suppose an "Are you sure?"
would not hurt, there are a great many commands that can prove
similarly disastrous. I'm not sure why this one needs it for than
others.

On the whole, I really don't care for this sort of hand-holding for
people who claim to be engineers. It's annoying and I doubt it buys
much. The "engineer" who did this in error probably THINKS he wants to
do it and would simply reply "yes".
