The examples are when it is possible to stream video and audio or if you wanna access two separate sink endpoints on the same device. The kernel AVDTP layer must to all sync and multiplexing work here and it is the only place where to do that in a sane way. However this is out of focus right now. The SCO and headset/handsfree support is different, because of the needed RFCOMM connection and the AT parser. Without the AT parser you can decide when to open the SCO link. It is actually broken by design.
