I'm thinking the target audience is other game developers. Most modern game engines have most of the features they talk about (the article really good about linking to sources), but those pieces are organized in a different manner so you end up with different restrictions, changes in performance, or scalability to different hardware / scenarios. The novel thing here is how they put together the pieces, not the pieces themselves. Most cutting edge articles are about a specific technique, so it's really good to see how it all fits together in an article like this.
