Fine, whatever.

Sure, but my point was, is, and always has been that any 3066-compliant
implementation won't see this as a country code (unless it is table driven,
which brings up its own set of issues).

No, what there has been is a lot of discussion of a real problem with no
apparent recognition of it as such by the draft authors. Your pejorative
characterization of this as "noise" does not make it so.

True but irrelevant.

(c) is frankly not an issue I care one whit about. (Perhaps I should, but I
don't.) I don't register tags. I write code that processes, and more to the
point matches, tags. That's why I have issues with this draft.

Again, your pejorative dismissal of other people's concerns does not
mean your position is valid.

Of course you can write a short piece of code to parse this stuff. It's what you
do with it after you parse it that's a problem.

Parsing almost never is. But simply parsing these tag is not, and never has
been, the issue.
