And your point is?  Should I conclude that NetBSD users see a seriously
lobotomized set of time zones, or does the packager just automatically
update the distribution list every time a new file shows up there?

In my former life as a packager for Red Hat, you'd list a specific set of
files you expected your package to install into, say, /usr/bin -- either
an unexpected addition or unexpected removal there should set off alarm
bells.  But the file list for tzdb's database would almost certainly just
be "/usr/share/zoneinfo/*"; there is no value in expending packager brain
cells on second-guessing the upstream there.  Maybe NetBSD's packaging
toolchain is too impoverished to do that, but I'd certainly call that
a bug not a feature.
