It looks like the data is focused on modern timezones rather than localities, which would mean a many-to-one mapping from zoneinfo. Unfortunately it doesn't look like there's enough overlap to allow an automated mapping.

No, but the Unicode consortium (I think) is keeping a mapping updated
manually. I'm using that in tzlocal, to figure out the local timezone
of the computer on Windows.
However, I think that mixing and matching timezone data in this way
from the two systems are likely to be full of pitfalls edge-cases and
complexities I do not dare even think seriously about. There will
probably be *less* errors by just keeping an old timezone database
around. Besides, what it they don't run Windows update? Then the data
still is outdated?
