Thanks for pointing this out - I wasn't aware of the intent there. Still, I see some legal issues. copyright.html defines Unicode data files to be the data files published under the following URLs: https://www.unicode.org/Public/ (except PDF online code charts) https://www.unicode.org/reports/ https://www.unicode.org/ivd/data/ license.txt says we have permission to redistribute modified versions of these data files. However, I don't see anything that grants permission to redistribute modified versions of <https://github.com/unicode-org/cldr/blob/main/common/supplemental/metaZones....> (the file you mentioned) as I could not find it under any of the abovementioned three URLs. I expect the intent was that we have permission to redistribute working data like that metaZones.xml URL even though it isn't part of an official release, but if so the intent should be stated formally. (I've learned to be cautious when it comes to copyright....)
