If you set your X server size bigger than your monitor size you can already do that. You can also move windows partially off the screen, so e.g. only the left edge is visible.
But I personally don’t see the use case. I can’t think of a time where the physical layout of different programs would be so important as to require a 2D canvas. Usually the connections between programs are not in a 2D plane, but instead by concept or task.
For example I may have a browser open, and want a terminal and an IDE next to it. How exactly these windows are placed is of no concern, I just need them to be visible at the same time . And that’s something I can achieve with a normal tiling wm already.
But maybe I’m just not creative enough to desire more complex window layouts XD
