The Locator is used for forwarding.
Surely the ID plays its part in neighbor discovery on the
final subnet, so in that sense it's used in the delivery
of the packet?
Indeed, in the common case of an IEEE 802 LAN, the ID is used
in IPv6 ND as an opaque index into a layer-2 bridge table for
delivery within the final subnet. Other link types might behave
quite differently; I doubt that ND is in use with all link types.
In any event, bridging is not forwarding. Even in the IEEE 802
LAN case, one cannot even directly bridge on the Destination ID
(since the ID might be derived from something other than the MAC
address of the interface attached to the particular subnetwork
specified by the Destination Locator). So the ID really is
just an opaque table index, even in the IEEE 802 LAN case.
