I would not characterize that as just "clicking a security box for non-notarized apps".

A few days ago I downloaded a non-notarized app. The dialog that I saw baffled me and it took me a while to recall how to run a non-notarized app.

You have to right-click on it and clock on "open", something that should be equivalent to double-clicking, but isn't. That's harder than clicking a security box. Someone with no knowledge might never find out how to run these apps.
