I'm not worried about the comments if that is what you are thinking
of. I'm more concerned about exactly what the output you are proposing
will contain - it is not clear to me.

At this point, I'm more interested in getting to a resolution that is
suitable for the long term. I've yet to see a willingness to engage on
backwards compatibility - to stop fiddling with the data. A key part
of that is engaging on the topic of what constitutes a minimum set of
IDs. Java, CLDR and probably more need that for their compatibility.
(ie. just reverting this one patch is insufficient to reach a stable
resolution, because of the unfairness of Angola/Slovakia)

Look at it this way, your patch (and probably previous ones) are
making a political statement of the kind you say you don't want. The
file `europe` contains full commentary for Germany:
yet Sweden and Norway get just 2 lines:
with the actual commentary relegated to the semi-trash can of
`backzone`. Where is the fairness in that? I'd also point out that the
file is structured by country, which makes a mockery of the idea that
timezones are not connected to countries.
