Oh, and, longer term, the Resurrection Stone is useful for recovering lost magics by interviewing their inventors and practioners. Every time an entire family on either side was killed off, like as not a family grimoire went lost along with its family-magic contents. What scions of now-dead clans, when summoned to chat, with the anemotional neutrality of the dead but for love and regret, wouldn't prefer their histories remembered and their magics taught to others who would remember their names with respect because of it? This goes well beyond the casualties of Wizarding Britain's Dark Lord Wars; cursebreakers could use the stone to interview the priests who worked the sites they're probing, to discover where traps are laid and treasure is hid. Wizarding archaeologists would find the Stone a vital tool -- given just one name to call, you could soon have a roster of a whole lost nation, and amass an intimate understanding of the customs and methods of that people. With the Stone, each and all of the dead become interviewable archives of their lives. Most of them would no doubt prefer their lives not be forgotten, so they'd be most cooperative.
