Is your proposal related to a problem?

On September 27 eslint-loader was deprecated in favor of eslint-webpack-plugin (see https://github.com/webpack-contrib/eslint-loader).
Some advantages over eslint-loader include the reuse of the ESLint cache and improved lint performance (see https://github.com/webpack-contrib/eslint-webpack-plugin#about-plugin).
