Dan,

The above sounds to me as if we are back to requiring that all
servers need to be upgraded in order to have things work
properly.  Certainly no DNS server deployed today does nameprep
before comparing names.  That assumption of massive, more or
less concurrent, upgrades, or its alternative, that we are
willing to tolerate a long-ish period in which things don't work
predictably, are the ones I though the WG concluded it could not
make.
