This is an optimisation. You don't have to enable it for network
file systems, or raw disk devices, or whatever else. Most programs
can't recover from a disk fault, or a network fault, so blowing the
program away when you fault to the bogus page is perfectly legitimate.
Programs that *can* recover can either be run in a lower performance
mode or be rewritten to handle this error.
