What problem does this feature solve?

currently rspack | webpack will generate the following result for modern-module, the comment is not nicely(Concate module seems hard to understand for normal users) to read, even minifier can remove these comments, but normally library code shouldn't be minified for better debug experience

;// CONCATENATED MODULE: ./src/answer.js
const answer = 42;

;// CONCATENATED MODULE: ./src/secret.js
const secret = 'rspack';

;// CONCATENATED MODULE: ./src/index.js



export { answer, secret };

//# sourceMappingURL=index.mjs.map

What does the proposed API of configuration look like?

there're some solutions, i'm not sure which is better

• provide a option to remove comments (like rollup don't have this annotation)

{
  output: {
      keepDebugComments: boolean // true means keep, false means remove
   }
}

• provide better comment annotation(like esbuild provide the simplest annotation)

 ./src/answer.js
const answer = 42;

 ./src/secret.js
const secret = 'rspack';

 ./src/index.js
