It's certainly better than the 200+ lines of JavaScript something like Webpack spits out when you statr a new project. I had to debug some of our project's build files and realized halfway through that my teammates didn't write this Webpack config monstrosity, Webpack generated it by /default/.
Sure, I can sympathize. That said, I've seen a bunch of "here's my results after upgrading to Webpack 4" tweets going around, and they all indicate much faster builds and somewhat smaller bundle sizes, with very minimal config changes needed.
