You make it sound so easy! Consider a 'simple' example — what might the effect be of a high speed, high mass 'drilling widget' be in such a body? Not much, probably, at least in the very short term. Cumulatively though? A device weighing a few hundred KG, rotating at a few thousand RPM for a few hours or days or weeks at a time? What effect do you think that might have on your 'quite simple' centripetal environment, floating as it is in zero g? Sure, it can be accounted for — but it's not 'pretty simple, actually'. Anything but.
