In practice, this isn't that much of a lockdown for most fedora users.
We give the default user on a system wheel access which means both
'sudo dmesg' and 'journalctl -k' work as is. While giving existing CVE
numbers that are easier/possible to exploit doesn't much matter
because they should be fixed already, It gets rid of a number of
exploits where you need information that is only available via oops
etc.
