How would we determine that?  There are millions of zones on the
Internet, and even if you managed to crawl all the public zones you'd
still miss stuff because of internal-to-some-network views.

Note that several different uses of the DNS conflict, too.  For
example, both Active Directory and Apple's Bonjour over wide area
(that is, DNS-SD) use labels that are not compatible with IDNA2008.
That's a mighty big installed base.  To see a discussion of just one
of the issues, see
