PRC assumed all of ROC holdings when UN recognition switched. Though really none of it matters, PRC / ROC is in an ongoing civil war over territories that both parties currently occupy. Historical narratives used to rationalize legitimacy and legality is just the veneer over domestic and geopolitics. While PRC having legal claims over TW helps, ultimately PRC will conduct even an illegal war over TW as police actions if it has to, just like how the US conducts illegal war around the world. The Chinese civil war never ended. At the end of the day, it's really that simple. If ROC/TW wants to hold on to what it conquered from natives of Formosa, they will have to defend it with blood. Ditto with Americans who think they can deter PRC on core sovereignty issues, when they couldn't even deter PRC from fighting over Korea while the US was a nuclear power. The west can craft whatever ahistorical story they want to cope, but until they commit to exchanging SanFrancisco/Sydney/Tokyo for Shanghai over Taipei, their opinions simply don't matter for PRC calculations over TW.
