Add a flag to prevent craco from overriding CRA babel config for files outside of src about craco HOT 4 CLOSED

When I add a babel plugin, it breaks IE11 support. Seems like Promise and Object.assign() polyfills are not included. Could that be related?

module.exports = {
  babel: {
    plugins: ['@babel/plugin-proposal-optional-chaining'],
  },
};

I dont think so, this one is about not applying customization to the loader that process the files outside of the source directory.

To give you a proper answer I would need time to investigate how CRA apply the polyfill.

CRACO only appends the plugins:

loader.options.plugins = babelPlugins.concat(loader.options.plugins || []);
