that's pretty fundamentally incompatible with the scrolling model of the web

It isn’t though. If browsers supported overflowing text into a “next” container (defined via hierarchy, selectors, whatever), designers could just design repeating pages of layouts like they usually do with full-height marketing stripes.

I'm not sure what you mean. The only way I can think it would feasibly work is if you have multiple columns with the same content, but offset by the window height. That wouldn't require any container linking and would allow you to scroll normally, but I also think it would be pretty weird.

Something like this: https://jsfiddle.net/n87hkdf4/

I think anything else would require tedious scrolling up and down all the time or worse - horizontal scrolling!

That offset would cut lines in half most of the times. Here is a visual diagram of one of examples of such layout:

  0vh
    margin
    column 1     column 2
    text         text
    text         text
    margin
  100vh
    margin
    column 3     …
    …
  200vh

Content flows naturally through column 1, 2, 3 and so on. No lines are cut in half horizontally (in a sense of overflow-y). When a window height resizes, content reflows accordingly - no scrolling required to read a full page at any window height.
