> Such arguments are always considered to have a default value of an empty dictionary
To clarify what I think @foolip is saying—because I tripped over it—an *"empty dictionary"* here isn't actually empty, but populated with its default values, which means all the following calls are indistinguishable:
```js
getDisplayMedia()
getDisplayMedia({})
getDisplayMedia({video: false})
getDisplayMedia({audio: false})
getDisplayMedia({video: false, audio: false}) // <-- what implementation prose sees
```
Having our prose interpret all of these as {video: true}` would be confusing.
I agree with others here that we should let `getDisplayMedia` fail here instead.
