Re: Character Variant Deployment at VeriSign
I agree with Adam; this is what I was trying to say some time ago (but
didn't say as clearly (and haven't had time to follow up on)).
Of course, existing registrations need to be grandfathered, but the
policy for blocking needs to be global to the zone, not on the basis
of individual languages for individual names.
