The first paragraph of the article says which configurations the author says you should not use (and which the nginx team agrees with from the e-mails)? I'm not sure a less sweeping recommendation would be good, especially since the details can be seen as "esoteric" (and thus you should make sure to understand them to judge a scenario more precisely)
I think the post is great, just that its not really clear what users need to do going forward (unsurprisingly; that should really be on nginx). In particular:
> Even pointing to a resolver on your internal local network may be a bad idea. Running a resolver on localhost is the only safe option.
In many cases, going to a localhost-only DNS is going to be way more complicated than getting off e.g. Google's open DNS, and thus conflating them likely means way more people giving up and sitting on untrusted DNS.
