My understanding of the overall situation here is that for 2.30 we try
to have Cyrillic->ASCII transliteration added into the built-in C locale
and after that we would discuss more about translit rules used by other
locales, and that this C locale patch is pending on Carlos to complete
his verification efforts.

Does the above sound correct to you?

Yes, the subject becomes overwhelming if considering everything related
at the same time so this sounds like a good approach, however are there
other notable open questions left around the C locale rules in addition
to this? (Ignoring the more generic tranlit rules or other locales for
the time being.)

It seems clear that there is no one right/wrong answer but it's a matter
of preference, especially the way this currently works. It might be an
improvement to output (for instance) SH instead of Sh if all the other
letters of a word are upper-case as well but not sure what would help
with the result being unambiguous.
