Understood...
But even a zip tool that isn't worth its weight in manure but is technically creating a perfectly valid ZIP, might exist.
Since I would anyway suggest scripting the EPUB zipping (much less typing of exclusions plus various magical incantations, and you can pass a directory + auto-name the EPUB), there is no loss in adding an extra line, and it doesn't really take
longer to zip... so why rely on "should"s? It is just generally a bad idea to rely on undocumented assumed (rightly so) behavior, but especially when there is literally no downside to being extra careful!
