The German Tank Problem springs to mind. While not precisely the same problem, it’s still a case where more information that necessary is leaked in seemingly benign IDs. For the Germans, they leaked production volumes. For UUID v7, you’re leaking timing and timestamps.

The rest of the ID will be random enough that guessing it will take an extremely long time, unless all the tanks were inserted in the same microsecond of course. I’m not sure this is a security issue with UUID though!
