It's not necessary to publish tzdb for every other years since the rules are predictable. Kyiv/Kiev follows E-Eur rules, and it seems like nothing is going to change in a foreseeable future. For Iran, it's another story. Current asia file has: Rule Iran 2021 2023 - Mar 21 24:00 1:00 Rule Iran 2021 2023 - Sep 21 24:00 0 - IOW, Iran normally observe summer time, and if the rule wasn't changed, they will observe DST in 2023-Mar-21 (their 1 Farvardin). However, Iran abolishes DST from 2023. Thus, there's no clock change in 2023. If we don't publish new tzdata by then, the tzdb is obsolete.

If we somehow get through this year's late silly season with no urgent releases, the current release will be out-of-date on 2023-March-21 (due to DST changes in Iran) so we'd need a release a few months before then to allow plenty of lead time for downstream maintainers and consumers.
So the fact that Ukraine DST ends in October 2022 does even bother you.
The time zone database currently has the region for Ukraine following EU rules, which specify that DST ends in October.
Has there been an announcement from Ukraine that they will be going on permanent standard time ending in 2023?
