But they're the ones that create all the noise.

How do you handle the meta-issue that it's disputed whether some of these
issues are even disputed? The government in Beijing will tell you that
there is no dispute about Taiwan: it's part of China. Other people will
tell you that there is a dispute. Similarly for Crimea. And I'm sure many
others. I can already imagine all the complaints that something "obvious"
is being falsely labelled as disputed. Equally, someone can raise a dispute
about almost anything: which disputes are you going to tag as disputed?

Of course you could.

As a simple starting point, you could try creating the list you want
*ignoring the pre-1970 data issue* and see how it maps to TZDB.

Have you asked them all?
