Yes and no. Since I've seen 2 for sure, probably a 3rd, they unquestionably do exist, so the issues are 1) opportunity for further study, 2) impact on them of discovery, and 3) impact on us of discovery. Regarding wanting them "discovered", the question comes down to whether the pluses for #1 offset the costs for #2 and #3. I don't think so, at least not today. For now, I'll do what study I can, personally, while avoiding the costs.
