I don't see how this is relevant for this discussion. If the .com
registrar decides to use a subset of 639 only, I consider this a valid
choice. No need to register any language tag with IANA; all tags
you ever want to use are already there.

Sounds like a reasonable approach; it appears that Verisign is using
it.
