An enumeration of the solutions of this problem space doesn't need to be done 
before the first live root zone key rollover.* IMO, there's little that could 
break and if there was any collateral damage it would happen in places where 
there's enough clue to put things right.

*Did anything significant break when the rollover from the DURZ key happened? 
OK, that was moving from a state where nothing validated to where things did 
validate, but still...
