A reason against the sysrq feature (maybe disabled by default)?

[Christian Hammers <ch@westend.com>]

Hello

I noticed that the MAGIC-SYSRQ feature is not compiled in in all kernels
although there were requests for it on this mailing list and in the BTS.

Is there any reason against it?

This feature is especially on servers very useful to shut down the
system with synced and unmounted partitions even if everything else is
no longer possible due to a crash.
(more features in kernel-source/Documentation/sysrq.txt)

Security considerations can be coped with by adding
  echo "0" > /proc/sys/kernel/sysrqecho "0" > /proc/sys/kernel/sysrq
by default to sysctl.conf.

thanks,
