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.
I am the king of knowing immediately when I have fucked up.
“Undo” has made us far too comfortable with mistakes.
Well the command is spctl, so I assume it stands for (s) Security (p) Policy (ctl) Control.
I agree that "ctl" for "control" is a bit weird but it's a pretty typical Unix convention: pfctl, networkctl, systemctl, etc.
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.
