This is a great point.

Also, we should be mindful that whatever solution should be vaguely applicable to other contexts where you’re selecting resources based on resolution, etc, such as video and CSS properties. I don’t want an explosion of attributes everywhere, and I don’t even know how you’d do that in CSS (background-image-1, background-image-2, …)
