I think the middle button paste function is very different from drag-and-drop. It's more like a auto-copy-clipboard. For drag-and-drop, the client that starts the dnd (therefore provide the data), should have focus but isn't(haven't been) necessarily selecting anything. While for middle button paste (or normal clipboard), the client that provide the data usually don't have the focus (unless it is the same client that receives the data)
The client that provided the data had the focus when the selection was made. And I have never seen a drag & drop scheme that did not either require the source to be selected (ie for text) or caused the item you dragged to become selected. So I really fail to see the difference.
In point-to-type the client providing the data loses the focus on the drop and the dropped client gets it. I think also there are clients that purposely grab the focus on drop.
IMHO, the middle button paste should be supported by adding a set of requests/events similar to those of selections to wl_data_device (just like the relation between PRIMARY and CLIPBOARD selection in X11). Since all toolkit support the middle button paste in x11 now, they should support these just well in this way.
Possibly but I think it is important that an attempt be made to merge the drag & drop into this. The middle mouse paste is far, far, more similar to drag & drop than cut & paste and if the api is not shared then I think there is a bad deficiency in wayland's design. If this means the api is shared with cut & paste too, then that is even better.
