The other question is whether the area that's moving to Moscow time is
same as the existing Europe/Simferopol zone?  The comment in the source says
"central Crimea" moved to Moscow time in 1994-1997, which implies that some
parts of Crimea didn't.

If they're not the same, does anyone know what the largest city is in the
area that was on Ukraine time in 1994-1997, but is moving to Moscow time

The other, politically fraught, issue for the tzdb is going to be how to
mark Europe/Simferopol and any other new Crimean timezones in zone.tab,
i.e. whether they should keep being categorized as UA or changed to RU.  My
suggestion would be to leave them as UA until such time as Crimea's
accession to Russia is internationally recognized, or the situation
otherwise changes.
