But the setting doesn't have to get rid of a warning, we're discussing requiring the right-click to even show the option of running the software.
Gatekeeper right now won't even allow you to run an application unless you somehow know and remember to right-click. This is sadistic. Many well-informed users won't even know about it and even more will forget to right-click on the first try. This is far from "forcing the user to make a choice about each binary". It's clear Apple doesn't want users to even be aware that there is a choice.
Well... there happens to be a way to disable that part of gatekeeper functionality if you want to. It’s just not a checkbox in settings, if I recall correctly it’s a terminal command that requires sudo. https://www.imore.com/how-open-apps-anywhere-macos-catalina-... But really, really only do this if you know what you’re doing. You can leave gatekeeper running but in a mode where it is much less restrictive. It may still prompt you if you just downloaded an app from Safari, that sort of thing.
