There's only one command line in a program and usually only one place it gets
implemented. So globals don't strike me as a mistake here. Also, there's the
matter of backward compatibility.

If there's a PR with an improvement, it's great to review it. But I don't think
we need to keep a bug report open on it just because "globals are bad design".
