I suppose it also depends on your current status. I myself managed (somehow very easily) to fade away over a decade ago. If now they decided to come after me by way of a JC I would just not entertain them. Putting it bluntly I would raise my middle finger to them and tell them to sit on it.
From my point of view to participate in a JC or to DA yourself is to acknowledge that you still buy into their system. From a family and freinds point of view the end result will still be the same. They will still shun you whether it be through fear of the consequences if they don't; or that they actually believe that "keeping the congregation clean bull."
I would say on balance however, were I forced into it that to DA oneself means YOU took the decision not them. My gut instinct however is that when you realise they have no real authority over you then to even play their silly games is to still give some kind of sanction to their authority. Like saying to them: "I acknowledge that you have the right to treat me like this." It's your life not theirs. They will do whatever they decide to do anyway, being brain dead zombies following Watchtower instructions.
DF'd or DA'd; different road to the same place. Don' give them the leverage, just walk in the opposite direction.
