I mean, I get the argument. But it falls easily, from my pov. If the styling is for all content from the target site, 304 still works logically. If the argument is "all content in the browser", it fails as it depends on the address.

And I can see the argument for either. If I increase my terminal's font and run a curl, the response is scaled up. That makes sense, I scaled up my terminal.

To that end, it is odd that scalling up is per document origin. I'm assuming that is configurable?
