Responding with stale data is, arguably, more damaging than failing
to respond at all.

So much so that the SOA expiry field serves to protect us from this
threat.

So, even though Randy is wrong for wanting to catch misconfigurations
by producing incorrect data, I also don't see where Joe is coming from.

If I hosted my domain with someone whose server was answering recursive
queries, I would probably use a lower value for expiry than I normally
would otherwise.
