How would that helped?  Well, it wouldn't.  The chance that you mess 
part of a RRset and rest of it will be OK is very small.

Well I thinkg, it's more dangerous for a TLD to have its NSs in 
different TLD since you are more prone to mistakes made by other people, 
and if you choose badly, your TLD can even be hijacked (at least on that 
particular NS).
