deprecating www as language code

And they also always live forever in BCP47. So deprecation wouldn't achieve

As for reserving other codes, it is also pointless. There are too many
in use, and about half of the code space (17,576) are already taken up by
language codes already. This is the same issue with the overlap of the
region and language codes; protocols and conventions need to avoid using
environments where language codes (or country codes) overlap with other
entities. If a domain label is going to be used for arbitrary language
codes, use it only for language codes.

(And as Doug points out, wikipedia deviates from BCP47 anyway.)
