The draft says 'Servers that do not tolerate unknown values will fail to interoperate'. But for extra queries that is not true. Certainly not if the extra query comes after the real query. It may not even be clear in what context the extra query should execute. After all the real query has finished already. Going back a long time when bind would report 'lame delegations'. By and large nobody knew what do with that. So 'These failures could be logged and be used to identify broken implementations'. It is not at all clear if something positive will happen if production servers start logging issues with remote servers. > You have time limited testing built into the code and controls to > turn the tests off. That is fine.
