No doubt, and there are all sorts of other things one CAN do.  One
common configuration is for enterprise AD servers to be delegated _tcp
for any number of reasons.  Operationally this happens, and in large
sites it is not uncommon to see TCP-based queries because of it.  How
wide scale is the issue and is any performance hit acceptable?  That is
a fair question and difficult to answer.  It would be perfectly fine
with me if the WG had said, “ok, we'll just manage that delay; records
cache anyway.”  But that is not how discussions went.  Delay is
important.  But here again, I think we could use more analysis.  That
shouldn't hold up this draft, however.
