No, I think John is arguing that IDNs at the top level are a good
idea, but opening things any wider would be bad. I think his position
is very similar to what Patrik argued, which was that we ought to
require people to show that there is not a harm before allowing the
innovation at the top level, rather than presuming that there's no
harm and reacting if we run into one.

A labels do _not_ conform to 1123. 1123 says "alphabetic", and all
A-labels have at least two hyphen-minus ("-") characters in them.
That's part of why we have a problem.

Maybe. That's what I was asking in idnabis about. It isn't clear to
me yet whether it is possible for an A-label (which is always
xn--[output from Punycode algorithm]) to end with a digit instead of
always a letter. I _think_ it's always a letter, but I'm not totally
sure. You can definitely have digits inside a Punycode-encoded label,
because I've seen them. We may want to restrict any A-label that
happens to end with a digit anyway, because of what might happen if
that label is exposed in A-label form, but in a BiDi context.

I am happy to report that I do not know anything about what ICANN
wants in respect of the contents of the root zone, and that I don't
yet think I need to learn.
