Load compilation output from webpack into assetgraph, populate, load in any newly discovered assets that webpack didn't pick up
So, webpack is not really good with non-js assets, especially anything that starts with html as an entry point. But assetgraph is.
At work I currently maintain a manually curated manifest of filed that need to be copied into the output directory after a build. favicons, serviceworker, web manifest, open graph images, non-webpack html-pages and all their sub dependencies
