China’s political leadership may not care about US reaction times, probably don’t in fact, but I guarantee you their military planners do. It’s their job to know stuff like that; strategy and wargaming scenarios require every scrap of intel about OpFor capabilities the planners can get their grubby mitts on.
Not that I think there’s any likelihood at all of an attack, of course. As I always say, why would they bother?
