The SA developers chose an appropriately small exclusion list
to hard code as the top 125 most often hit whitelist entries.
Those top hits are largely invariant and would represent a
large portion of the DNS queries if not excluded.  It doesn't
make much sense to serve up a small, nearly invariant list
with a DNS list, long TTLs or not.
