| * otherwise, the destroyed contract's slot is reset to 0, charging the same gas as `EXTCODEHASH` and `SSTORE` when resetting storage, while also refunding the amount specified in `SSTORE`. | ||

| `SELFDESTRUCT` is modified to not clear contract storage. | ||
| This change also works retroactively: all prior destroyed contracts can be cleaned up. |

Should probably discuss in the discussion-to link, but it seems like all self destructed contracts prior to this change would already have all state cleared so this statement is a no-op effectively.
