I think that this could be a boon to pixel tracking. From my understanding, a site could embed multiple tracking pixels on a page to give a good approximation of how far the user scrolls and how long it takes them to scroll down the page, all without JavaScript.
I would be curious if this would also be apply to email clients that render using Chrome.
