The way things currently work you can use 'nofail' when you want your
boot to be unaffected by a missing device. If we change this as you
suggest, then a missing device will lead to a long timeout (which
delays boot by a couple of minutes). That's not really wrong (it
doesn't contradict the fstab manpage), but would obviously limit the
usefulness of 'nofail'.
