I think the main problem is that there are several different "status quos". Predominantly there is the "international status of Taiwan" status quo that Beijing cares about and the "no conflict in the Taiwan strait" status quo that the US focuses on. Add to this the fact that identity, political influence, economic power, and regional/global military strength are all in a state of flux while the CCP has demonstrated that it is unconstrained by international agreements or basic facts... and it becomes much harder to predict stability.
