Well, I think more accurately we have years of software that relies on emergent behaviours of the prior default of certain implemnetations. > While pedantically it may be true that these should be treated as unordered > sets I don't think that's being pedantic. That's literally the definition of an RRset, and (as I guess has been shown by others in this thread) relying on an existing order behaviour to which one has become accustomed is going to be a problem even if people just switch out their software or change the configuration of their systems. This is a bug in the relying software, because the network _never_ made the promise that software was relying upon. > Software should have safe defaults that matches common expectations. I think this is true only if the common expectations are reasonable ones, and given what RRsets are the expectation in this case is not a reasonable one. What you're really saying is that, if there was ever one dominant system on the Internet (in this case, BIND), then the standards all need to be rewritten to conform not only to what that software implemented (a position with which I have some sympathy) but also to conform with the default settings of that software (a position I think needs rather more support than you've offered). > is that the order of results is NOT consistent. Sure. "Unordered sets." > In many environments, this > lack > of consistency is relied upon for systems to work properly. To me, this is like saying that, in many environments, the order of TCP packets (which very frequently do come in order) is relied upon for systems to work properly. This is true, but still broken. > This ambiguity in the current specifications What is the ambiguity? There is only an ambiguity if you think that people's expectation of something nobody ever promised them is part of the specification, and it isn't.
