As I said, I have no objection at all to making the prefix be zh-Latn
instead of just zh; I would prefer it. It is Michael Everson who wanted "zh"
instead, so perhaps you should address him on this topic.

(For my part, I think it is more important to have the subtag registered --
and not have this drag out forever -- than for the subtag's Prefix to be
perfect; in practice people will use Latn as a prefix anyway.)
