As a laptop user, I would like the ability to Drop & Pickup the secondary display from a non-focused to a focused workspace position. This will allow your everyday common laptop user to detach the secondary display’s previous static workspace position reference, and attach to the currently focused workspace position.
In other words, a keyboard shortcut to toggle ‘workspaces on primary display only’ or ‘workspaces on all displays’ options as are currently available in gnome 40.
