The tz maintenance rules as written clearly said that each country should have at least one zone until 2019. That rule started being broken in 2013

If I'm reading the tzdb history correctly, from 2013–2019 the guidelines said only that there should typically be at least one name (not Zone) for each inhabited ISO country or territory. From 1997–2013 the guidelines also talked about names, not Zones. (There were no guidelines in this area before 1997.) So it appears that there has never been a guideline saying that each country should have at least one zone, and this means no such rule was ever broken.
