That's too much extra work. With multiple monitors you can maximize primary apps while still having manual management of smaller supporting apps on another monitor. You also get more edges for rapid snap to the sides of a monitor.
I use 3 monitors but would switch to 1 if games respected the dimensions and 8k displays could refresh at 360Hz.
it has quirks and limitations, some of which can be fixed by disabling system integrity protection but it can definitely handle window tiling and navigating with keybindings when you use the companion daemon https://github.com/koekeishiya/skhd
