> Our existing UN M49-based region subtags that begin with “0” are already subject to this.

If it hasn’t been a problem over the past 10+ years for existing and in-use numeric region subtags, it’s not clear why we would need to change anything for hypothetical variant subtags.

I understand the intent, although there are plenty of opportunities already for confusion.

I have a colleague who often refers to the bogus tag ”en-EN” by analogy with “fr-FR” and “es-ES” and “it-IT”. (The organization doesn’t fully get that region subtags aren’t always necessary or desirable.)

Our existing UN M49-based region subtags that begin with “0” are already subject to this. One of them, “en-029”, even has some currency. I don’t know if there has been any confusion around the leading zero. I know from a quick web scan that there is plenty of confusion from people who think a region subtag can only be an ISO 3166-1 code element, or who are still stuck in RFC 1766 and think a language subtag can only be two letters.

I appreciate the nemawashi and suggest that we try to not enact any firm decisions, but keep this idea in mind whenever an all-numeric variant subtag is being floated.
