Changthang is mostly there to give prettier borders for people controlling Tibet. You could well argue it should be wasteland but cutting it up into more pieces won't happen as the area it represents isn't really settled even today.
It's one of the more inhospitable places on the planet and afaik the only population at the time would've been a few thousand nomads and their herd animals moving back and forth across the Tibetan Highland.
