One of the point of Linus is that most of the crashes will not be because of an active attack but because of a possibly latent bug that sometimes appear and might very well be non exploitable. So probably people running server would like to have everything working instead of having random crashes on processes or drivers that are not the core of your service but can affect it. And given the size and complexity of the kernel it would not be strange to have these crashes appear only on certain setups and not necessarily on the ones of the people that are testing it first.
