The history of timezones has some existing cases where a specific timezone has been renamed. For example, the Asia/Calcutta timezone has been deemed obsolete and replaced by Asia/Kolkata.
In Ukraine, according to international standards, there is a timezone called Europe/Kiev. The capital of Ukraine is officially and internationally should be spelled as "Kyiv". "Kiev" is an incorrect version that emerged a long time before the Soviet Union collapsed in 1991.

We have a really large community of programmers that would like to start the process of renaming the Europe/Kiev timezone to Europe/Kyiv. We understand that it will take a long time for everybody to transition, but it has to be done in the long term.
