 From my point of view, as the person who handles tzdata updates 
for NetBSD, I would prefer to have no controversial changes in any 
tzdata update ever.

I suggest that a possible way of achieving the goal of no 
controversial changes, would be to have at least two branches 
in the upstream repository.  I'll name the branches "proposed" 
and "approved" for the sake of this message.  Changes could 
be committed first to the "proposed" branch, then merged to 
the "approved" branch after discussion.  Releases would be 
made from the "approved" branch.  I also like the idea of 
avoiding potentially disruptive changes during the busy times of 
March-April and September-October.

If we had already been using this scheme over the past month 
or so, then the Fiji and Liechtenstein changes would be in the 
"approved" branch, and would be released soon, while the changes 
that some people are unhappy about would be in the "proposed" 
branch, and would be discussed further, and possibly reverted or 
modified.

Of course, any OS vendor can do its own separation of changes into 
different categories, and merge only the uncontroversial tzdata 
changes into OS release branches.  The question has never come 
up before, for NetBSD, because we have not been aware of such 
controversial changes before.
