These emoji tag sequences don't derive their stability from ISO 3166-2.

The emoji tag sequences depend on: CLDR Unicode Locale Identifiers, and 
more specifically, for these subregions, on the unicode_subdivision_id:

http://unicode.org/reports/tr35/index.html#unicode_subdivision_id

And the data for that is here:

http://unicode.org/repos/cldr/tags/latest/common/validity/subdivision.xml

The stability for such tags is baked into the CLDR repository, as I 
understand it.

By the way, if anybody is looking, Pomerania is there: "plpm" among the 
4925 other valid unicode_subdivision_id values. So:

Flag of Pomerania = 1F3F4 E0070 E006C E0070 E006D E007F

But alas, that is not a *valid*  emoji tag sequence (yet), so no soup 
for you!
