The "min" in "zh-min" was the first(?) extlang subtag, before anybody thought of designating anything as "extlang". But it clashed with an existing ISO 639-2 identifier. So, when extlangs were created and specified to use ISO 639, "zh-min" got left behind.

But harmless. There is probably not a single application, present or future, that would ever use the new, "preferred" regular tag; they would all stick with "i-default". BCP 47 assures that they may do so; SHOULD NOT is not MUST NOT.

I'm OK with that. Comments can be added or removed at any time.

I stand corrected.
