I'm happy to defend the security aspects of this module, if that's
what's concerning you.
I do know that there are quite a few people here who want to be able to
do remote sysrq -- they used to have a "crash trolley" consisting of a
PS/2 keyboard and a monitor. Unfortunately most of their new machines
only have USB and you can't hotplug a USB keyboard in many of the
circumstances for which you want to (for example) trigger a crash.
I guess that also means I'm happy to produce valid use-cases.
