don't know if it's still on the table, but Andrew has hinted that the unused variables error may in the future still produce an executable artefact but return an nonzero return code for the compiler. And truly fatal errors would STILL produce an executable artefact too, just one that prints "sorry this compilation had a fatal error" to stdout.

Same for kernel drivers
They are indeed dangerous, and I think this is a pretty good example of why.
