I was much happier when SysRq-L didn't kill the system, and I could still sync
and unmount the filesystems afterwards.

I still don't understand exactly why this behaviour was changed - someone
suggested that it was because with init dead, orphaned processes couldn't be
assigned to be children of init.

I don't see why that means we have to kill the kernel completely though, rather
than just assigning them to the next running pid.

If I was aware of the reasoning, I'd put together a patch which did the above.
But as nobody has documented the reason for the change, even upon being asked,
I don't know whether it's worth it.

So could I repeat my question: Why was the behaviour of the kernel changed?

And ask another: If I produce a patch which fixes it again, so that orphaned
processes will become children of the process with the lowest PID, will such
patch be accepted?
