Not an issue, just a comment - node.js 12.17 introduced a relevant (experimental) API

See <https://nodejs.org/docs/latest-v16.x/api/module.html#source-map-v3-support>.

```js
import module from 'node:module';
const sourceMap = module.findSourceMap('./my-file.js');
const position = sourceMap.findEntry(1, 1);
// run file with the `--enable-source-maps` flag
```

Of course, it _is_ experimental, and I don't know if it works with CommonJS scripts.
