Just wanted to mention that the URLs of the form
http://iso639-3.sil.org/code/eng are also a fairly recent development,
and - as far as I know - did not come with any commitment of SIL to
keep these stable. But then, they probably carry enough semantics to
serve as a human-resolvable identifier even if they don't resolve for
machines anymore.
