Is the "as" needed in "early hints" response
What about if we had:
Server response:
HTTP/1.1 103 Preload
Link: </style.css>
Link: </script.js>
Loading: </ball.jpg>
since it doesn't matter what the content to be preloaded is, that will be determined later when the html page is sent. For example the case for type="_javascript_" since we don't actually know what type of script it is anyway from the "early hints" you mentioned, but that doesn't matter either.
Also we could have a "loading" item to display while the page is being loaded. This could be a jpg, gif, even a small flash file.
