See for example this failure on Jenkins. The test created two content items with Subjects, and querying for all items without a specific Subject. This used to return 1 item. But now it returns 2, because the Plone Site object is also returned, which has no Subject set. This object used to be ignored in the catalog. See zopefoundation/Products.ZCatalog#148
What is a bit strange, is that the 'not' query does not return any results when I run it at the beginning of this test, so before any item with this Subject has been set. That might be a problem in ZCatalog still.
Note that the GitHub Actions tests will fail because they use an older Products.ZCatalog. So I am making a PR in
buildout.coredevto update the pin and make a checkouts of this PR branch. If that is green, I can merge this PR, and update the ZCatalog pin in the coredev buildout and dist.plone.org.
