Good to know ;)

Now it executes 2 separate queries, for "seen" and "unseen" articles. It
is possible to avoid executing of both queries for the case of unchanged
group (no new articles), because IMAP server returns total count of
articles in group within answer to SELECT command. Some other speedups
are possible also.

That's interesting. Can you tell me how do you customize Gnus in your
~/.gnus (agent, cache, etc)?

AFAIK, it was always so. May be I'm wrong, but I'm seeing the same thing
in Gnus w/o any regards to patches. It was so at least in Emacs pre-22.

Well, it needs some special flag to detect old vs new backend. It looks
like ugly solution for me :)

Cool! Thanks!

Ok, will do.
