It generates a FilesystemMeta.fsmeta container with a readme that states: “A filesystem metadata snapshot contains information necessary to investigate reports of issues with disk space”, along with a couple of commands. The .fsmeta is around 20 MB in size. In the feedback assistant, there’s a disclaimer at the bottom stating that the logs CAN contain personal data, that’s why I am asking what personal data can they contain, not if. My mac died, so I cannot check the full content of the container from my iPad. If someone else wants to check, you can generate it by trying to submit a feedback and selecting the category Incorrect behavior>Settings>iPhone/iPad storage.
