Sorry, it's still incomprehensible to me.  (I am skipping over the 
Russian text, and reading only the English parts.)

I see things like "Suggested new zone: Asia/Barnaul, split 
from Asia/Omsk" but I see no explanation of how the rules 
in the new Asia/Barnaul zone would differ from the rules in 
Asia/Omsk, or why.  A little research tells me that Barnaul is the 
administrative centre of Altai Krai, which is a region of Russia, 
but that too was not explained in the message.

Perhaps if I could read Russian, "the changes as written down in 
the Russian Wikipedia" would mean something to me.  Could you

I also did not understand your usage of "contiguous zones", 
because it was not clear that you were using "zone" in an 
unfamiliar way.

The whole message was unclear.  Perhaps if you translated the 
Russian parts, and wrote the English parts in full sentences, it 
would make more sense.  Also, with my new understanding of what 
you meant by "contiguous zones", I may now be able to figure out 
the original messages, but I am not motivated to do so.

Regarding the first half of your sentence, I see no problem with 
one of the main maintainers deciding that it's more important 
to fix rules that affect current timestamps than it is to fix 
rules that affect timestamps in the past.  I won't respond to the 
implied accusations in the second half of your sentence.
