​Three safety locks the last time I used it. After inserting the magazine I
had to load the bullet first, then I had to unlock the gun and then I had
to pull the trigger. I don't think that this procedure happens accidentally.

​Because you don't think about it dosen't mean others think about it. If
you build scripts that provision systems after minimal install, doing
thinks like yum -y update, reboot and do cleanup like yum -y remove kernel,
it works fine with yum but completely crash your system with DNF. Of
course, you can wrap around this ​and build you own checks, but why should
the checks be implemented in the scripts if the current update manager
already provide this kind of checks and features?
