This seems worse then remembering, because you still have to remember that your safe-by-default command is unsafe-by-default everywhere you're not usually.
The presentation suggested in this very thread would work better for me. I generally pay pretty close attention to package apt/pacman/dnf output because it is all right there in front of me.
Perhaps ironically, if those programs asked me for each change I would just hold Y until it went away. Needing confirmation of each item is why I glaze over.
