Before jumping to conclusions, you need to remember that all you have seen of the code table for ISO 639-3 is *draft*.

Is there a choice at present?

There will be indeed a change in the 639-3 code tables: macrolanguage mappings from zza to dlq and kiu will be added.

This is not a "mismatch" as you had in mind. It is a new macro-language entity for which the component members were already in 639-3. That's a possible scenario that will have to be considered in developing 3066ter, but I don't think it is a particularly complicated problem to deal with.
