Sadly, fault-tolerant clusters where you can tolerate the loss of a single machine aren't the norm. There are many (MANY) server applications or industrial use cases that do not handle random kernel panics very well. I still prefer "crashing" over "silently ignoring critical errors", but you cannot generalize it like that.
