But that’s not changing the design, really
Depends on what one means by “change the design”. It doesn’t make a fundamental change to the deeper architecture of the game, no. But it does require some relatively superficial changes, which are themselves a design problem of sorts.
I agree with your conclusion (recognition should be based entirely on who has Actual Control, in cases where that can be clearly determined), but not with this particular explanation. Nobody “recognises” Taiwan, but it has nothing to do with believing it’s illegitimate or unrepresentative. It has to do with the fact that China has a hissy fit if you do.
