Yes. Lameness can result from various different errors, but if
BIND spits out a lame server error, it seems to treat them all
the same (AFAIK), even if they give an answer to the question

Since lameness can be enough to stop recursive resolvers asking
that server for answers, all lameness should be dealt with
urgently, before gangrene sets in.
