You aren't tied to only referencing things from JS: you can have Webpack emit a manifest file with a JSON object mapping from the original filename to the hashed one. Then oldschool web app code can reference these fingerprinted files using the manifest. To fingerprint files you normally wouldn't import in JS, you can 1) import them in JS anyway just for the bundling side effect or 2) use a Webpack copy plugin to copy all font files, for example, to the build directory and fingerprint them.
