If one uses a manual tiling window manager like i3 or sway and a large monitor one can divide the screen into separate work areas that each host multiple applications based on their role in one's workflow and use less workspaces.
Scrolling makes a similar but different workflow practical on small screens where flexibility matters.
Most workspaces are a fullscreen browser or some other app to the left, fullscreen editor in the center, tmux on the right.
I still use tiling within a monitor to view email side-by-side with browser, or a document or two side-by-side with code. Rarely feel the need to put 3+ apps in a complicated layout on one screen since I’m usually not gonna be cross-referencing at them all at once.
If I had one monitor I wouldn’t want to be taking up half of it showing the browser all the time when I could instead use that real estate for more vim splits.
