In the light of morning, that still seems like a fine idea to pursue
long-term. But I doubt we have time to make it happen before our
November releases, and even if we did, I'd be really hesitant to
put such a change into the very last release of v14.
So what I now propose to do is commit my 0001+0003, that is just
update findtimezone.c's data to be traceable to current CLDR.
If nothing happens on the more-ambitious idea then we can add
the script from 0002 at any later time.
