If that's the case, the pairing with Hades (a game with strong metaprogression) muddles the point. As I mentioned in another comment, DCSS doesn't have "bones" to loot and it will generate ghosts regardless of whether you've actually played before, so the impact of previous runs on future runs is essentially cosmetic.
