That's why every behavior should be controlled by a configuration switch. No solution is universal.

And, if you cannot positively answer those questions for your zone and your three or four slaves, well, what can you expect from the Internet as a whole ?

We're talking about people who want to publish signed zones. You don't need to be an expert to answer those questions. Or, on the other hand, you probably should not publish your signed zone before you are able to answer them.

We agree to disagree then.
