Allow me to dig into my historical outhouse of ideas, one moment... https://datatracker.ietf.org/doc/draft-jabley-dnsop-dns-flush/ The minutes of the dnsop meeting at IETF 87 contain recorded feedback on draft-jabley-dnsop-dns-flush that was overwhelmingly negative, including the phrase "the worst idea I have ever heard of" from Johan, I think with reference to the general idea, not the proposed mechanism, and "I quite like it" from Warren, so make of that what you will. I see that Warren and I subsequently took the time to write up https://datatracker.ietf.org/doc/draft-jabley-dnsop-flush-reqs/ but I think we lost interest at some point after writing it. The slides I used included part of Randall Munroe's xkcd-1133 "you have a bad problem and will not go to space today" without permission, under the title "Requirements Analysis". Slides from IETF 87 no longer seem to be on-line, which I think is a shame but which also at least avoids the obvious and very reasonable copyright complaint. Your draft is surely better than mine, but I thought I'd take the opportunity to bathe in the historical disgust of that moment once again. Joe
