On the contrary, if you've laid out two screenfuls you can guess that

I wasn't talking about guessing at visibility. I was talking stuff like
this:
<!doctype html>
<div style="height: 100vh"></div>
<img src="something">
<div style="position: relative; top: -50vh"></div>
Where should that second div be placed? Should the user be able to see
it? You don't know until you know the image size.
In this case, User agents would obviously need to test if the latter div
would be visible if the image was monopixel. Such complications would be
bound to add up as we take more features into account; the optimization
may well not be worth the complexity.
And it gets even worse when tables are involved, because an image
arbitrarily far down the table can affect the table column widths and
the width of the whole table and the site probably depends on particular
widths.
I surrender to broken websites.
