I don't believe I've ever used middle-click to close tabs before you mentioned it, so I wouldn't call it intuitive. It's not near as documented as Ctrl+W is (which self-documents in traditional menus). And it doesn't work for all tabbed interfaces: it fails in gedit, gnome-terminal, nautilus, and epiphany-browser.
