Actually, all of this is premature. Until RFC 4646bis is completed and
approved, all we can do with regard to language subtags is:
1. Register primary language subtags that appear in ISO 639-1 and -2,
with no consideration for, or awareness of, ISO 639-3.
2. Create and register primary language subtags under very, very
exceptional circumstances which are unlikely ever to come to pass.
3. Create and register variant subtags.
which are more or less directly associated with language.
