Can you be more specific? What users (e.g. people registering
domain names, end users browsing the Web,...)? Significant to
what degree, according to whom? What are the actual consequences?
(Any pointers to documents, similar to those given by Stephane,
Also, as far as I understand, there are many other differences between
ccTLDs. Some are very strict in whom they accept for registration
(e.g. requiring some legal proof of residence,...), others are very
liberal. Some hand out second-level domains (e.g. .de, .ch,...),
others hand out third-level domains, or both second-level domains
and third-level domains (e.g. .co.jp, .or.jp, .jp)). Also, policies
and checks against registering similar domain names (such as
GOOGLE.example vs. G00GLE.example), and conflict-resolution
procedures sure will differ quite a bit for different ccTLDs.
It might be very easy to claim:
"The resulting user confusion is significant and the
retroactive imposition of remedial policies is not a viable means for
addressing this problem (nor is simply dismissing or tolerating it)."
and then go on and try to revise the RFCs for ASCII-only domain names.
As far as I know, nobody is asking for changes for ASCII-only domain
names. What makes IDNs different?
In my opinion, due to the fact that IDNs are much closer to the very
wide human cultural variety, the chances are that the need for diversity,
at least for some aspects, may actually be greater for IDNs than for
ASCII-only domain names.
