Those optional (but official) rules previously mentioned. We wouldn't discard them much the same way we wouldn't say anyone's no longer adhering to D&D rules by using any of the other optional rules, so, they're officially printed rules, just an option most people don't use.Where?
Frankly I think the Neverwinter Nights example's a bit better at it because that's designed whole longstanding worlds around the idea of occaisonally just having a DM hop in and spice stuff up a bit for the players
