Which package?

I encountered it in intl-messageformat, but it's probably present in additional packages

Describe the bug

The ESM version is referred to only with the module field, but that is not part of the Node.js spec and will only work if you first bundle the code. You must include exports for the ESM version to be accessible in an unbundled Node program

To Reproduce

Load intl-messageformat from a Node script without a bundler and it will load the CJS version rather than the ESM version
