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. paul
