Some ideas like the 'controlled but not owned' territories (ie West Bank etc) are a bit more difficult to do from both a player and user-interface perspective. It's something that can get confusing when you're playing.
Regarding government types, I'm not sure there is much to be gained by separating American-style Democracies from Parliamentary democracies from socialist-democracies. The latter can be approximately simulated by setting your political leaning to left wing, and while it is true that we don't really simulate an American system (even in the US the in-game elections are now a three party system), the real-life American system is a bit of an oddity in the world. (In fact, trying to simulate Washington is a game in itself
