Should .wasm file be included to overridden unityInstance.Module.cacheControl()?

Unity documentation says about the general rule “Typical candidates for the WebGL cache include large files and files that use a custom file format.”, However, I’m not sure 100% if we should explicitly cache the .wasm file manually or if Unity did this job automatically.
Apart from that, we explicitly cache .bytes and .bin files.
Since we keep everything in bundles we don’t need to cover assets files in the overridden method like mp3 and others.
Does anyone know what popular format of files should be cached or about pitfalls related to this topic?
