I'm wondering more about the practical problem of what happens to places that are in the list now, but won't be then. And I don't even mean the contentious aspects. It's one thing to replace "Scotland" with "United Kingdom" because for now officially Scotland is still a member of the United Kingdom and the UK is the entity that is a UN member, regardless of how some of the Scottish people identify, but what about "South Georgia and the South Sandwich Islands" which you can pick now and some people did? It belongs to the British Crown but is not part of the UK, yet not part of another UN member country either. It's not a contested situation like, say Kosovo. The UK does not say it is part of the UK. Do you just put it there for the purposes of the country list? Blank the field instead?

It's not so problematic with places that right now already don't exist, like Isle of Man is not on the list now, so probably if people care to be precise enough to pin down that they are in a Crown Dependency, they already use the other fields, and it won't exist in the new list. But in other cases the current list allows that pick. Like I suppose Puerto Rico may affect a number of people too.
