Why sysrq is limited to only "sync" command on official fedora kernel?

>it is nothing someone is using regulary and that settings are security settings recommended by most auditing tools

security part is admit able, but still I think it is too much strict,
e.g. what is security problem of having 'r' request enabled?
(specially considering that fedora uses relatively unstable
gnome-shell)
