I'm asking the BIND team for a better answer, however my best understanding is this will query a second root server (typically next best by RTT) when it gets a non-validating answer, and assuming the second best one validates just fine there are no further follow on effects. So you're talking one extra query when a caching resolver hits the root. We can argue if that is minimal or not, but I suspect most end users behind that resolver would never notice.
I'm not talking "one extra query", and it's not simply about subsequent transaction attempts either - so conjecture aiming to marginalize the impact isn't particularly helpful. I.e., have that look, get back to us... :-) -danny
