I think it's a bit farfetched. A lot of individuals demonstrated the abilities of chakra absorption, but there's no clue to say they are all related to Dark Release or other KKG (except for actual KKG-based chakra absorption abilities like Rinnegan's Preta Path). Oro seemingly mean it's not very fair ability for Sasuke - Yoroi's opponent - at that time (because of the Cursed Seal problem he had then). Besides, Dark Release KKG is not cannon.
