my use-case was the desire to just export a spreadsheet of all folders and files within the document library, and Source Analysis appeared to be the way to do that. If I analyse the entire Site Collection and export that as a spreadsheet, I will then need to filter out all irrelevant sites, pages, libraries, folders, files. Perhaps a Library Analysis could be added as an option?

This feature would be beneficial especially if you are trying to identify what content are in the library and for us to export the inventory spreadsheet. Without this, we would have to manually export to Excel from the site.
