This does not make things easier. In any way. CEOs die suddenly all the time. It hasn't changed anything ever in terms of how corporations are legally required to operate.
You can kill a CEO a day and the legal issue does not change. They will not put people over profits just because people are dying. Why that isn't clear yet I don't know.
You saying "CEOs die suddenly all the time" to prove that nothing will change is idiotic. CEOs aren't murdered all the time and you have nothing to base your claim on. In any case, I see no harm in the path.
