If they are made a part of the standard, then the various DNS 
implementations will be expected (reasonably) to implement them. And they 
then become a standard operational tool, making DNSSEC little better than 
the current certificate process.

If recursive, caching nameserver operators have to roll their own 
implementation to achieve the goal, it keeps NTAs contained. Sure, some 
people will go to that trouble, but unless they have a well-defined 
reason to do so, most won't.
