That is a bet am willing to take since there's an inherent acknowledgment that there are enough spies within and without the civilian-military-business sectors in Taiwan that such a potential move must and should be anticipated by the PLA planners. And if you and I average Joe's can think of such scenarios then I don't see why can't the PLA planners do the same, whose jobs after all is to think of every possible contingencies for decades. It's even possible to interdict the possible route of the civilian leadership by executing a missile strike if capturing them alive is less than possible to ensure that they're not going to have the Zalensky effect.By the time Taiwan's declaration is made public, the Taiwanese leadership would be deep underground in a bunker in the mountains.
Also, the moment the civilian leadership announces the illegal declaration of independence, China should not even entertain any diplomatic overtures from any country, especially from the U.S. because that would just be a possible delaying tactics to evacuate and prepare the Taiwanese renegade leaders for safety. The PLA should immediately, and decisively attack key infrastructures such as communication, electricity, internet, create a total black out in the island in conjunction with the decapitation strike, in tandem with special forces strike to ensure the capture of the strategic targets.
But in order for the PLA to execute and achieve the operation objective of capturing/decapitation the political leadership, the PLA has to make some kind of feignt maneuver or targets to divert the attention of the civilian and military leadership in Taiwan. I feel that if the initial Russian special operations in Ukraine was executed in such a way where a total blackout and diversionary tactics/attacks were made, then there is a remote possibility that the paratroopers, special forces tasked to wrestle the Kyiv government could have been achieved.
Instead, the line of communication was allowed to remain open which made the operational security of the Russian forces along with their movements that much difficult to conceal. Everyone in Ukraine was essentially going on social media broadcasting the Russian forces movements to the world. And since the Americans were already providing ISR to the Ukrainina forces that simply made the lives of the Russian forces extra difficult and deadly. Fighting with one tied behind your back both literally and figuratively was a head scratcher in my opinion.
The PLA can't and must not afford to make the same namby pamby approach to their potential operations in Taiwan. And I hope to all the gods that war doesn't happen.
