It looks like that's indeed what happened. Thanks for jogging my memory.
So I guess it wasn't an omission so much as an awkward and
- Asia/Phnom_Penh and Asia/Vientiane (which had existed prior) were
combined with Asia/Bangkok on 2014-10-04 in
- Asia/Hanoi (which had NOT existed prior) was added to backzone on
If we had known about the differences in Asia/Hanoi at least one release
prior to this merging (and I recall all of this came up as part of the same
discussion), then Asia/Hanoi would have needed to become a separate zone at
that time. But because we first took the opportunity to coalesce the other
zones, Asia/Hanoi's history could be coalesced as well, which is why it
landed only in 'backzone' and not in 'asia'.
I do think this boils down to a judgement call, though. There certainly
could be an appearance of bias (though none was intended, it simply wasn't
necessary to include Asia/Hanoi for backwards compatibility as it hadn't
yet existed). Given that and the other complexities here, I would
personally be inclined to move the Asia/Hanoi into the mainstream
distribution, but I can absolutely see how others involved in the
maintenance here may disagree. At the very least, better documentation in
the 'asia' file is a pretty clear must.
