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."
