Standard behavior in Compiz allows for configuration of keyboard shortcuts. When specifying a new keyboard shortcut for an action, Compiz informs the user if the key combination is already in use. However, for the hardcoded keyboard shortcuts (e.g. Super-t to open Trash), Compiz is unaware they are previously bound. Thus Compiz freely allows the user to change a keyboard shortcut to one already hardcoded to a Unity function, which is confusing for the user. In general, Unity should not hardcode any keyboard shortcuts anyway, instead opting to provide defaults configurable via CCSM, but lacking this, Unity needs to at least reserve the keyboard shortcuts via standard means in Compiz.
