Sure it is fair. The fact that some operating systems had extremely
simple/primitive file systems without any caching means that those systems were
capable of surviving file device pulls. But it isn't reasonable to consider
that a feature. RT-11 was in fact an unusual example in its days; few if any
operating systems of that era had a "just yank it" property.
