I also have things I want to change in gatekeeper, but that feature is not one of them. Just gut feeling but I would say 110% of all users, would just click ”start” on every unsigned app if it was that easy.
they could do it like they do it for accessibility settings. you have to opt in for an app and you need to know damn well if it is a reputable app before giving those controls over. there's enough friction in that that it is not done by many apps but not hard enough that it's a huge ask to whitelist the app.
I don’t understand what you mean by “protection”. The “protection” offered by Gatekeeper is that you aren’t able to run unsigned software without going into System Preferences. That’s it. There isn’t some other secret sauce.
Without Gatekeeper, macOS will instead pop up a dialog warning you that the application was downloaded from the internet, and provide an option to run it anyway, on first launch.
I am the king of knowing immediately when I have fucked up.
“Undo” has made us far too comfortable with mistakes.
