And I have been wondering why it doesn't push the CSS to Webpack as well. There is no way in the foreseeable future that Rails could do without JS and hence Webpack is mandatory. We might as well push it as default or easily enabled / disabled via options.
It's clunky to build CSS 'packs' and it's unclear how to wire in asset helpers e.g. checksum'd file names for images. It's not insurmountable, but there is no obvious best path forward.
