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.
