I guess this is because of #7398, and a .js entry point needs to be exposed until we get JSON Modules.

I want to fix this—we shouldn't break previous usage—but can you provide a little more context on the error itself? How can I reproduce this?

1. Create a new directory
2. Initiate a new npm package with the field "type": "module"
3. Create index.js with the content import bcd from "@mdn/browser-compat-data"
4. Run node index.js
