I strongly disagree. The DNS protocol has its own built-in redundancy, 
and changing addresses for TLD servers is not prohibitively difficult. 
So I see no reason why they should have PI addresses, especially since 
there is a significant number of TLDs and they all use several 
addresses. If those addresses would all become PI this would probably 
double the IPv6 routing table size at this point. (Granted, it's very 
small now, but still.)

If TLD servers are anycast that _could_ be a reason for giving them PI 
space, but I think the TLD community first has to come up with 
coordinated plan for this, rather than just start giving out PI blocks 
and play "voldongen feit" game. (Sorry, it's monday morning, can't 
think of the English translation. In French it's "fait accompli".)
