This suggests that you should consider reversing the test i.e. allow the 
ones deemed to be safe and block the rest by default ("fail safe"); this 
is what good firewalls do, as you are protected from future (and unsafe) 
additions.

Of course, you'll have to extend the list where necessary, but you'll have 
to do that with future unsafe commands anyway.
