I think the phrasing is unclear because "this response is not required to
work" is ambiguous. The response *itself* doesn't have to work?  Or the
resolver can get along without this response?  I took it to mean the
latter, but I see how it could be confusing.

I'd suggest something like "this response is not strictly speaking
necessary, as it provides no information the resolver didn't already
have; resolution can succeed without it."
