I have a draft of approximately what was published which is available to CalConnect members as part of our involvement with ISO, and I had a look through it just now to double-confirm my memory.

It says very little which is relevant to this work - most of the changes are around ways to specify ambiguous dates or period longer than a day (e.g. 2021-W15 is the week that we are currently in, 2021-34 represents the time period from March 1 to June 30 this year, XXXX-11-26 represents my birthday without specifying a year).

In particular, it doesn't do anything with timezones, calendar scales or calendar systems - it's Gregorian only.

So apart from the greater-than-4-digit year problem, there's nothing in ISO8601-2 which would benefit this work.
