No. I will set the ID for Southern Min in ISO 639-3 to be "nan"
precisely to provide backward compatibility with this pre-existing
registration. I will also include a macrolanguage ID "min", again, to
provide backward compatibility.

Where there is an IANA registration that uses an alpha-3 to extend an
ISO 639-1/-2 ID, like "zh-min", I have planned to include that ID in ISO

I had not though about doing that for registrations using "i-", such as
"i-tao" -- just hadn't occurred to me. Some (e.g. ami, hak) already
matched Ethnologue, but a few do not.
