If there is a DatagramSocket or DatagramChannel bound to a multicast 
address then it has be possible to connect to that address too. So we 
may need it for the connect methods - that should become obvious once 
some sets up an environment and starts to extend the existing tests to 
bind to IPv6 multicast addresses.
