Create a local.css file?

Would you consider changing Analytic to support a local.css file, to make it easier for users to keep up with their CSS customizations in a single place?

How it works:

1. in analytic.info, include support for local.css last, so it overrides every other CSS file included in Analytic
2. In the Analytic package, provide a blank local.default.css

If users don't need it, they don't set up local.css. If they do, then their changes end up all together in a file that isn't overwritten in theme upgrades. It's a neat idea I've seen in a few other themes, such as acquia_marina, and I love it.
