Well, I have to confess that this response doesn't make any sense to me.
I don't see how it is relevant whether ntpsim is a simulator or not.
If root (or heck, any user) ever executes ntpsim, then the vulnerability
in ntpsim could be exploited by a non-root (or heck, any other user)
to do things that the attacker shouldn't be able to do. That's not good.
This is a risk if ntpsim is ever executed on any multi-user system.
If you meant to say that "ntpsim is only a simulator and will never
be executed by anyone on any multi-user system, ever", then I accept
your statement -- but if that is not what you meant, I can't understand
