I remember somebody championing css features, I think Adobe, to make it possible to have overflowing content spill over into another container, like it is (was?) possible to do in Publisher. I'd love something like that, and have wanted it several times. But it was abandoned...

Never knew that. I think that in combination with CSS grid auto fill, that may have solved a huge chunk of paged columns.
