I try not to do that for any X. The tz project has succeeded in part 
because it is not run by the UN or by any other official agency. The 
'Theory' file says "The tz database is not authoritative", and I try to 
keep politics out of the data, so that we avoid the sort of bureaucacy 
that being "official" would entail.

In practice, tagged revisions on GitHub are just as "official" as 
tarballs on IANA. This doesn't at all mean that I've given up on IANA; 
it's just how things work now.
