Now I'm confused.  Since time immemorial (well, OK, about a decade)
I've been configuring all my name servers to answer authoritatively for
  127.0.0.1 PTR localhost.
and
  localhost. A 127.0.0.1

I'm *quite* sure that I read copious documentation and I'm supposed to
be doing that.  Has practice changed?  Have I (and countless others)
been misunderstanding the documentation for years?  Or am I
misunderstanding your post just now?
