That's just the way you write the rules being deprecated, not the functionality.
There is move left/right within a workspace, move to specific workspace and then move to next/previous workspace (from memory using e+1 as the workspace name in the command but might be misremembering). Admittedly this isn't exactly the same as what you want; I replied from my mobile and checked when I went back to my desk. I usually use meta/shift/[num] to send to a specific workspace though as I make heavy use of them.
