### [REQUIRED] Describe your environment * Operating System version: macOS * Browser version: _____ * Firebase SDK version: 7.0.0 * Firebase Product: empty-import ### [REQUIRED] Describe the problem Every time I type "undefined", VS Code auto-imports ```ts import undefined from 'firebase/empty-import'; ``` This started happening since updating firebase a while ago, and is really inconvenient for the dev experience. The only thing [empty-import.d.ts](https://github.com/firebase/firebase-js-sdk/blob/master/packages/firebase/empty-import.d.ts) seems to be good for is to set the `typings` field on various packages (e. g. [here](https://github.com/firebase/firebase-js-sdk/blob/b4ee745b4ed7a4f4a95acd08c9e384868ae4dbae/packages/firebase/installations/package.json)). Can't it ```ts export = {}; ``` instead of `export = undefined`? Thanks!
