Embedding of 3rd party widgets asynchronously:
<script async src="3rd-party-widget.js"></script>
Then the script could find its node in the document and replace it with
whatever it wants.
Another use case would be a (superficial) emulation of document.write()
for scripts that have been embedded asynchronously.
