I would be rather hesitant to put such a feature in place. Already now there are too many colleagues around for whom high numbers seem to be the only thing that counts – leading to boring copy paste logs and, what’s worse, to lots of fake founds on caches they have clearly never seen – maybe because they want to cheat themselves, but more likely because with this "production line caching" they simply seem unable to keep track of which ones they really found. Introducing a possibility to do mass logs would make this even worse as it would remove the last potential alert mechanism, namely the minimal effort to have a quick look at the listing and the last logs: if the latest logs are a series of DNFs, it’s very likely the cache was not there – and this happens a lot with (often badly maintained) powertrails.
