Done . . .
Looks quite interesting; however Idk if this would solve my issue (or I 
don't get its purpose exactly). I don't intend to use complete "sets of 
workspaces" (like topics?), rather switching both screens at once when 
changing workspaces (to avoid client-screen swapping).

Anyway,

addRawWSGroup :: WSGroupId 
<https://hackage.haskell.org/package/xmonad-contrib-0.17.0/docs/XMonad-Actions-DynamicWorkspaceGroups.html#t:WSGroupId> 
-> [(ScreenId 
<https://hackage.haskell.org/package/xmonad-contrib-0.17.0/docs/XMonad-Config-Prime.html#t:ScreenId>, 
WorkspaceId 
<https://hackage.haskell.org/package/xmonad-contrib-0.17.0/docs/XMonad-Config-Prime.html#t:WorkspaceId>)] 
-> X 
<https://hackage.haskell.org/package/xmonad-contrib-0.17.0/docs/XMonad-Config-Prime.html#t:X> 
()

has drawn my attention . . .

And yes, since Plasma wanted to re-invent the virtual desktop, dual-head 
screens are now seen as two separate ones, which can be individually 
customized with different wallpapers and bling such as "Activities".
