Let me see if I can summarize the new state of affairs:
639-3 provides 3-letter identifiers for languages.
639-5 provides non-overlapping 3-letter identifiers for collections of
639-2 provides a subset of the codes in 639-3 and 639-5 representing the
"important" languages and collections.
639-1 provides a subset of the codes in 693-2 representing the "very
important" languages (and collections?) and giving them 2-letter
identifiers as well.
RFC 3066 successors should allow any 639-3 or 639-5 code except those
which have 639-1 equivalents.
