I understand the rationale (although the root cause is that HTTP,
stupidly, does not use SRV records and instead rely on the 'www'
convention), but remember that, even if ISO 639 changes the code, RFC
5646 rules (section 3.4) will still make the code live forever (even
if it is with "Deprecated: 2011-04-08" and "Preferred-Value: wwx").
