So, what did that zone cover? Central Crimea?, why then, the new name says "Crimea"?

Sorry, I don't recall, but I expect it had something to do with Sevastopol naval bases 
and/or city observing Moscow time regardless of what the rest of Crimea did.  That usage 
is already supported by TZ='Europe/Moscow'.  Moving forward, I thought it would be less
confusing for tzselect users if the description said just "Crimea" for the time in 
non-naval-base Crimea, since the folks who want to set their clocks to Moscow time far 
into the distant past should already know to use TZ='Europe/Moscow'.  
Plus, "central Crimea" wasn't quite right either, as the Simferopol zone is more 
than just the central part of Crimea.

So, it is more than the central part. But what is it?
