This makes sense. 

However, there would also be much room for abuse. For example, this code:

  div {
    overflow-style: paginate;
    height: 600px;

would be a terrible user experience on a small screen -- you'd have to
scroll to find a button to press to get to the next page.

On the topic of buttons, where do they go and what do they look like?
Having a UA-provided simple set of buttons would make sense, but -- as
we know -- some authors want pixel-perfect control.

The 'vh', which refers to the height of the viewport, may be helpful
in making scalable designs:

  div {
    overflow-style: paginate;
    height: 0.8vh; /* or something */

How could it overflow? A tall image? We could make rules for that,
e.g. that scaling or clipping is required.

I'd hate to have layers and layers of scrollbars inside pages inside
scrollbars etc.
