Dear Pavel (I suspect, that this is your real given name and you use Paul only because it's more popular ;-) ),
Thank you for your answer.
I'm sure, you know better what to do. Thanks for supporting TZ database all this time. As always, you do your best.

I just would like to share my incentive to appeal.

 
Maybe Kiev is more popular for exUSSR population and the rest of the world (because the Russian language is more popular, and, as you know, 'Kiev' is a transliteration from russian 'Киев' and 'Kyiv' is the transliteration from ukrainian 'Київ'), however, as a Ukrainian, I feel irritated every time when I have to choose my timezone and see the wrong spelling (in my country we have the only one official language, it's Ukrainian and, e.g. all road signs, IDs and official documents use transliteration from Ukrainian, not from Russian).
