Some of us have both publicly-facing authoritative DNS, and inward facing recursive servers that may be open resolvers but can't be found via NS entries (so the IP addresses of those aren't exactly publicly available info).

Just proving my point - you didn't find the webpage that also lists their IPv6 addresses. :) Now explain how you find a recursive nameserver that isn't listed in an NS entry and *hasn't* been publicized someplace that Google can find it.

That might, must *might* mind you, be somewhat tangentially related to why I asked Jared what the BCP is for dealing with mobile devices with hardcoded DNS lists. :) (Otherwise read as "we'll be glad to fix it if somebody has a brilliant idea on how to do so without generating more calls to the help desk than the near-zero rate we currently get about DNS amplification issues"....)
