I'm glad to see they are using gulp. I know webpack is the hot new technology, but in my limited experience with webpack, gulp is easier to use and is more intuitive. Webpack has a lot of loaders, but I feel like gulp gives more flexibility out of the box. When I want to do something with gulp that I don't know how to do, I feel like it is easier to implement with gulp, because gulp seems to be a bit lower level. I noticed that they updated the docs for webpack since I last visited, so maybe I will try again.
