Sorry, I lost track of the context and forgot you were talking about the new classic mode, rather than stock GNOME Shell (which doesn't have launchers on a panel).

The panel in GNOME shell also is lacking an ability to add/remove/re-organise launchers with the mouse. It's not incapable of supporting launchers though...
