Vendors that wish to, should be able to experiment with prompt-bundling by detecting multiple invocations of getDisplayMedia on the same JS task today, e.g.:
```js
const [choice1, choice2, choice3] = Promise.all([
  navigator.mediaDevices.getDisplayMedia(),
  navigator.mediaDevices.getDisplayMedia(),
  navigator.mediaDevices.getDisplayMedia(),
]);
```
They could satisfy such simultaneous requests using a unified picker with checkboxes. This would be backwards compatible with other browsers where users would see 3 prompts one after the other (or until the user cancels).
