I am not surprised of Hu Chunhua not getting the Premier role but it is unexpected for him not making into the Politburo. The Communist Youth League of China is completely out of China highest political decision making circle which is not totally unforeseeable buy sooner than I expected. CYL has been very problematic for many years and there seems to be little has done to reform CYL. CYL has not only become irrelevant but ideological detrimental to CPC.
To be honest, Xi consolidated of power has probably been hastened by the new cold war that started by Trump and Biden. Without the external pressure, I don't think Xi could have that much of domination of the new Politburo. It is like I told you so when Hong Kong, Xinjiang, trade war, covid, Taiwan, Huawei and the recent semiconductor bans have proven Xi is right and the liberal lefts are naive.
