Is there really a difference between a TAR saying "no TA exists" and  
"I have no TA for this TLD"? From the perspective of those running or  
using the TAR, these two statements would appear to be effectively  
identical: the TAR has no TA for the TLD in question.

I agree with Joao that adding this new requirement is unrealistic.
