Well, personally I only see any of this making a difference if the system
console is publically accessable (ie, library computers or something.) - This
is definately not the most common use, IMHO.

If it crashes without sysrq, depending on how badly it crashed you might have
been able to sync/umount/reboot and not have to fsck or lose any data.

Well, this requires a recompile/reboot. ('Okay,' you might say, 'But you had
to reboot anyhow if it crashed.', that's true. But you still do not have to
recompile. Besides, if the X server crashes, you don't have to reboot the
system if you can just slam alt-sysrq-r, then run something to reset the
video mode.)
