Software is still free to provide knobs to deviate its behavior from
RFC, which is nothing unusual when it comes to DNS(SEC).
Is there a real problem to solve? My understanding is that this document
is stating what software should do by default.
DNS software has so many knobs which are either not described in any RFC
that I do not see why this document needs special treatment.
