In my opinion if the cylinders are removed and no work done on them (such as removing the cylinders to gain access to the lower end) then they need not be honed or re-ringed. Our shop did this many times on propeller strike inspections for example. In this case we would slide the piston out far enough to remove the piston pin. This was done when the conditions warranted: engine was within manufacturers recommended TBO for hours and years; engine compression and oil consumption was normal; no outward signs that something was amiss with the cylinders.
It is sound policy to replace the rings anytime you hone the cylinder.
