Radiant AI is in Oblivion and every game they've made since then. There's nothing to enable. The issue is primarily with the game content; it's used all over the place, but in the final game it's not very impactful.
By “in its entirety” I mean as it was promoted and originally demoed. The release version is vastly different to the pre-release demos (some are linked in the article)
Yes, I wrote the article. I wouldn't say the system in the release version is vastly different to the pre-release demo (there was only one to my knowledge, the E3 2005 one), as that just demonstrates a tightly scripted sequence of events, which one of the developers was open about even before Oblivion was released. Some things about the system definitely changed (such as disallowing NPCs to pickpocket from the player), but I don't think we have any evidence of whole systems or major behaviors that were actually implemented at some point and cut before release.
