This is excellent advice. There's something I really dislike about import "./style.css" into JS files - it just seems meaningless especially if you've worked with other languages/ecosystems. A great many tutorials default to this style, so it'll likely live on for a while.
As yet another tiny UI framework creator (forgojs.org), the switch to esbuild-loader was our best developer experience decision. create-forgo-app (our CRA equivalent) takes 3-4 seconds, and running it is instantaneous. Faster builds actually change the way developers write code.
