This! So much this! I've spent the past few days thinking about making a "Webpack Cookbook" with up-to-date "recipes" for getting the job done, such as how to use SASS, add linting, hot reloading etc. Mozilla have definitely made my day :)
I might be in the minority, but I'd rather not learn all the idiosyncracies of Webpack, I just want to build my project and get on with my day. Webpack have done a great job with the documentation for v2, but it remains a complex beast.
