Hmm? Syncing is allowed to my knowledge. C-a-d and gdm allow a clean reboot/poweroff. But sysrq does an abnormal reboot/poweroff, which we cannot allow. Similar, remounting read-only is also security senstive, which we cannot allow. Without being logged in there's very little you can do on a host right now, and sysrq should not open up more there by default.
