The current tzdb release has already changed spelling from Europe/Kiev to Europe/Kyiv. The other Ukrainian locations' spellings shouldn't matter as they are planned to be removed (actually, moved to 'backzone') in the next release, as their pre-1991 data entries were most likely wrong and so they were out of scope for the database.
