The first sentence reads:
"The set of languages, calendars, and countries that are supported in
the date formatting functions is implementation-defined."
"Implementation-defined" is a fancy way of saying "the committee
couldn't agree on a realistic interoperable solution".
Good luck researching country-specific Julian/Gregorian roll-over
dates and new year rules. The current country codes don't cover for
example Venice adopting the modern new year rule at a different time
than Rome.
And good luck supporting calendars that even ICU doesn't know about.
Non-Gregorian calendars are a huge can of worms. Let's put the lid
back on right away.
