I was agreeing with the quoted text - I believe that any serving of 
stale records must be predicated on the presence of a valid delegation 
from the parent zone.

Serve stael must not become a vector whereby malware can keep its C&C 
systems artificially alive even if the parent has removed the C&C domain 
name.
