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... :-)
