We found nothing better for backwards compatibility in 4646.

...minimallly better. Another tack could be "only for 639-2".

IMO the best idea, after all it's not very different from
registrations of variants. 

An ideal example was the registration of "nqo", just get it 
right a.s.a.p.  And "fy" + "frr" + "frs" were counterexamples,
there was never any doubt that all sorts of Frisian are written
in the Latin script for a very long time.
