There's a bunch of open questions about this state. If a window is CSD-drawn, does it include drop-shadows, or should the compositor draw drop-shadows?
If the compositor should still draw drop shadows, what happens if the client uses ARGB32 to get rounded corners, how does the compositor efficiently calculate a shadow? Does it take the alpha channel of the composited pixmap and do a blur on the GPU (your rounded corners look fine, but your transparent terminal is a bit too dark)? If the client draws the shadow, how does the WM decide where the boundaries of the window are for snapping / maximization? It would be awkward to drag the window to the left and see an invisible shadow edge tile. To solve this I proposed a client-set _NET_WM_FRAME_EXTENTS property on this list a little while back, but didn't hear any response.
