This would be a lot more readable if we could include, say, a name field, but doing so would create lots of extra rows of diffs where those names aren't the same in each source. Ideally we'd like a way to say "We don't care if the name is different, but we would like the name field included for any row where the ID field differs"
If we're only comparing a very small number of columns — perhaps even only one — and the values are only IDs (and might be missing in some cases), then the resulting output can be quite baffling, and largely unusable: e.g. https://www.wikidata.org/w/index.php?title=Wikidata:WikiProject_every_politician/Italy/Deputies/prompts/OpenPolis/comparison&oldid=609580809
