Since I wasn't able to attach those before the two images show how simply dragging the recycle bin icon right upto the position will see a new shortcut added. Not shown there however is a very small message prompt asking to add shortcut to Quick Launch. The second shows how that went.
The main reason it was eliminated from the 7 taskbar makes sense in that you can simply drag just about any desktop item right onto the taskbar without fuss.
On XP and Vista the quick launch bar was rather limited once filled with tiny icons while you can pack a large number on the new version for that and still see them retain size. Just take a look at how those appeared on the Vista quick launch once I filled that up with several seen in this image.
