Evidence that a small town of 500 (I'm guessing 100-200 households) can self organize some urban infrastructure doesn't contradict narrative of Xia state hydrology that operates on completely different scale and coordinated between different tribes. 9/10 of the archeology team were from PRC and fine making pronouncement that a few hundred people can get together and do home owner association tier stuff. The drama over King Yu / Xia historicitiy is whether his mythos / achievements was game of telephone. Whether he exists at all and hence whether Xia should be considered as China's first dynasty where ruler successfully tamed water. Whether that comes later is matter of debate, but I don't think anyone has seriously suggested a large culture (i.e. millions of people over vast territory) can self organize huge, sprawling capita projects without centralized authority.
