i've been helping folks configure DNS RPZ on their recursive name
servers in a way that reverts .PROD lookups to the previous NXDOMAIN
behaviour, thus fixing their apparent stub-resolver client breakage. of
course the real problem is using nonqualified names, but since that has
worked reliably for several decades, we can expect a long tail of
adaptation. for the time being, and perhaps for a long time to come, the
people who call the presence of .PROD a bug and/or depend on its absence
as a feature, outnumbers and will outnumber the people who call it a
feature or who will call its absence a bug.
