This looks good to me as far as the code goes; I don't have any visibility into downstream affects of this though.

I don't have any visibility into downstream affects of this though.

Even if this does affect anybody downstream negatively, the configuration should allow a very easy compatibility. I would consider it best practice to not use default logging configuration for production deployments anyhow, particularly if you are relying on the logs (e.g. if you are parsing them)
