The correlation only indicates that poor code tends to have more

I would argue that eliminating unused variables always improves code
quality. If you have unused variables you are wasting the compilers
time, confusing anybody who reads your code, and possibly making the
resulting binary less efficient. Nobody is arguing that it is the
mythical vampire-slaying silver bullet. (At least I hope not)
Yah, code quality wasn't specific enough. I meant code correctness.
