Yes, I would expect that there’s a better way to do this. But as-is this doesn’t get in the way simply because it requires the buffer-local variable to be explicitly set.

I would imagine the flaw with this is that there are probably a lot of different ways buffers get killed, and a key binding is only one of them, so it would only offer a little protection.

Would this be better accomplished by setting the variable via a mode-hook?
