This should be able to achieve the same goal.
One thing I can think of is what mentioned by Sergey that some sysrq handler may want to print out something, but it should mostly be covered by 2 other panic debug print patches, which will print out task/mem/timer/lock/ftrace info runtime on demand.
Well, not all sysrq handlers just printk stuff; some do sane things, like emergency sync, umount, etc.
