looks quite invasive to the whole sysrq interfaces, it trickles all the way down into sysrq.c's handler prototype, affecting 20 prototypes.

It might be called from a serial console on a soft-locked-up system, having no physical access to the system. Having a hung reboot in that scenario is not really productive.
