Names are retrieved through aliases, so I think there is no need to add extra names in the COMPAT resource bundles.

% ./build/macosx-aarch64/jdk/bin/jshell -R-Djava.locale.providers=COMPAT JAVASE

CLDR incorporated the Kyiv/Kiev aliasing in their upcoming version 42, JDK does not have the alias yet, thus:

%  ./build/macosx-aarch64/jdk/bin/jshell JAVASE                                 
|  Welcome to JShell -- Version 20-internal

jshell> ZoneId.of("Europe/Kyiv").getDisplayName(TextStyle.FULL, Locale.US)
$178 ==> "Kyiv Time"

jshell> ZoneId.of("Europe/Kiev").getDisplayName(TextStyle.FULL, Locale.US)
$179 ==> "Eastern European Time"

jshell> ZoneId.of("Europe/Kyiv").getDisplayName(TextStyle.FULL, Locale.JAPAN)
$180 ==> "Kyiv時間"

jshell> ZoneId.of("Europe/Kiev").getDisplayName(TextStyle.FULL, Locale.JAPAN)
$181 ==> "東ヨーロッパ時間"

jshell> ZoneId.of("Europe/Kiev").getDisplayName(TextStyle.FULL, Locale.JAPAN)

This will be fixed once we incorporate CLDR v42 into JDK repository. Since we don't backport CLDR, TZ backports should separately cherry-pick the changes in timezone.xml, such as:

diff --git a/make/data/cldr/common/bcp47/timezone.xml b/make/data/cldr/common/bcp47/timezone.xml
