Well, that's a new feature for a funeral that I haven't heard about before, so I'll be interested in the answers you get. Grandma used to have a rule to live by in such situations: "When in doubt, don't." When I post an obit here I delete the names of the survivors, so I don't think I would do it for the reason you cite, at least not right away. You can always change your mind later if the circumstances seem to warrant that.
