Just two remarks

1st one: point 4 (Unicode subdivision codes listed in emoji Unicode site)
arises something like chicken-egg problem. Vendors don't easily add new
subdivision-flags (because they aren't recommended), and Unicode doesn't
recommend new subdivision flags (because they aren't supported by vendors).

2n one: What about "Adopt a Character" (AKA "Adopt an emoji"). Will be
valid, but not recommended, Unicode subdivisions codes eligible? For
instances, say, could someone adopt California, Texas, Pomerania, or
Catalonia flags?
