Just what *is* that purpose?  I don't see any indication in RFC 1034; no 
real justification is given for its existence.

Note also that the OP has made a big deal about whether it should return 
records with cred=GLUE, but the DNS specification makes no mention of 
credibility levels for cached information.  All it says, in section 
5.3.3 (the resolver algorithm, which is used by a server when processing 
a query that has RD set) is:  "Step 1 searches the cache for the desired 
data. If the data is in the cache, it is assumed to be good enough for 
normal use."
