Right.

As a bit of historical context that some reading this may not have,
the origin of IDNs involved the same story that Orie's bit of
research showed, with a focus on such global identifiers as postal
standards for mail being sent out of the origin country.   At least
from my perspective, we ended up with IDNs because a few ccTLDs
announced, and started using, non-ASCII domain names at the second
level and beyond.  Even those who believed that was a terrible idea
--again for the reasons that are at least implicit in Orie's summary
-- were convinced that, if people were going to do non-ASCII DNS
labels anyway, interoperability considerations strongly argued for
everyone doing them the same way rather than having one method per
country, with some using UTF-8, UTF-16, or some ISO 646 variation,
all in different ways.  Hence a single (we intended) IDN standard.

Again, this is not a syntax twitch.  It is a decision to go (or not
go) down a path that, at best, involves complicated relationships and
tradeoffs and, even under the best of circumstances, some
interoperability and human confusion risks.  If that decision is made
in favor of non-ASCII (or even non-numeric) identifiers, one has to
sort those relationships out and specify was it to be done about them.
