I agree :)

Two other issues I noticed when trying to rewrite my draft to stick to
terms in this document is:

"DNS Forwarder" is the only term prefixes with "DNS". I'd wish we could
just use "Forwarder".

I see no term for "Recursive Server" - there is one for Authoritative
Server. And the term "Resolver" oddly means something else (which after
reading it in the DNS Terminology draft, just makes me weep.
