| - New `--webpack-no-externals` flag added to `build` and `start` scripts. It disables scripts' assets generation, and omits the list of default externals ([#22310](https://github.com/WordPress/gutenberg/pull/22310)). | ||
| - New `--webpack-bundle-analyzer` flag added to `build` and `start` scripts. It enables visualization for the size of webpack output files with an interactive zoomable treemap ([#22310](https://github.com/WordPress/gutenberg/pull/22310)). | ||
| - New `--webpack--devtool` flag added to `start` script. It controls how source maps are generated. See options at https://webpack.js.org/configuration/devtool/#devtool ([#22310](https://github.com/WordPress/gutenberg/pull/22310)). |

We need a way to filtering those flags. We did something similar for puppeteer. We could whitelist them to not pass to webpack (jest fails when you pass it unknown flag), too. I’m fine with renaming
