Continuing the discussion we had about IPv6, multicast and destination options. In a multicast case only the final receivers of the packets (i.e. the nodes joining to the multicast group as end hosts) would examine the Destination Option. I am not sure if this is the desired behavior? On the other hand a Hop by Hop option would be examined by all intermediate nodes whether they are PREF processing or not. Whcih one you would think is a better approach?

When using unicast and things like segment routing the behavior of the nodes is more straight forward. The processing of the Destination Option is done each time one of the routing option destinations are reached.
