It's certainly not very plausible.  The Ethnologue (and with fair
probability the ISO 639-3) code for Southern Min is CFR, so depending
on how RFC 3066ter ends up being designed, we'll either have cfr or
zh-cfr.  ISO 639-3 codes aren't going to have substructure, and the
chance that one of them will match an existing grandfathered code
exactly is just about nil.

Or so I was going to say until I looked up the Ethnologue code for
Hakka, which is HAK!  So unless that gets changed, hak will indeed
become a productive rather than a grandfathered tag.
