Question about rebuilding an engine...

I have the motor out of a 92 Saturn SL2 that I recently bought for my younger daughter. With only 128,000 miles in 15 years, it was an oil guzzler, so I figure on replacing the piston rings. The original cross-hatching is still easily visible to within 1/8th inch of the top 'sweep' of the top compression ring. I cant feel any rim-ridge, (and I know that .001" of ridge can be felt with my thumbnail.)
So.... why should I bother to run a hone into these cylinders? and since the pistons just slid out the cylinder tops when I pushed on 'em - why should I run my ridge reamer around there? I think my reaming and honing might make the cylinder worse. ???
And though the oil control rings were not 'stuck' in their groove, they didnt expand out like the compression rings did, or like new oil control rings do. They expanded-out much less than a millimeter.

No reason to hone or ridge ream. Very common for the original hone to still be visible on these engines. Re-ring it and call it good. Did you check your bearing clearances? Easily done with some Plastigage.
