Subject: sysrq_always_enabled boot option ??

This is about commit 5d6f647fc6bb57377c9f417c4752e43189f56bb1.
Why is this change needed. As far as i understand from the
the commit message distro used to set sysrq_enabled = 0.
But they if we need sysrq support we can set it using sysctl
why do we need a kernel command line option ?

userspace occasionally disables it. Also, sometimes i want to boot
distro images without changing anything in them.
