 prBody: |
+  When a user have an existing CommonJS package like this:
+
+  ```js
+  // foo package:
+  module.exports = function foo () { };
+
+  // ESM users get...
+  import foo from 'foo';
+  // CommmonJS users get..
+  const foo = require('foo');
+  ```
+
+  Now that `require(esm)` is possible and they can ship ESM to their CommonJS users without breaking them, they would try something like this:
+
+  ```js
+  // foo package
+  export default function foo () { };
+
+  // ESM users get...
+  import foo from 'foo';
+  // CommmonJS users get..
+  const foo = require('foo').default;   // <--- This is now different!
+  ```
+
+  As you can see, for CommonJS consumers this will not be exactly equivalent. Since in ESM the default exports is a property of the name space, they need to access `.default` from the result returned by
+  `require(esm)`. So the idea is that Node.js can take a marker from package authors to directly customize what `require(esm)` returns in this case.
+  To keep `const foo = require('foo')` working, the two proposed markers are:
+
+  ```js
+  export default function foo () { };
+  export const __cjsUnwrapDefault = true;
+  ```
+
+  or
+
+  ```js
+  export default function foo () { };
+  export { foo as "module.exports" };
+  ```
+
+  Note that to follow up with this vote, there is [a proposal](https://github.com/nodejs/node/pull/53848) to reuse this marker for detecting whether the imported module is CJS.
+  There is no consensus on whether that is the right way to solve the problem yet ([see](https://github.com/nodejs/node/pull/53848#issuecomment-2244500584)), so this vote is just about
+  the marker naming bikeshed.
+
+  The vote should stay open for 7 days, or until all TSC voting members have cast a ballot.
