I'll hold off on most other questions until the PRI appears.

Hopefully the MA will adhere to the new 50-year limit. The example given
in the proposal talked about trans-national flags.

Well, the codes are the same, but you're defining a new syntax, so you
get to remove the hyphen if you want to. But again, the proposal didn't
say that.

I didn't know that was relevant to flag tagging.

Of course not. I'd also not expect CLDR or Unicode or even vendors to
keep track of every state and territory flag around the world. Vendors
will support some subset of flags of their choice, just as they
currently do, and that's consistent with existing Unicode principles
about not having to display every possible character.
