Instead of just renaming it, I reconsidered what the API should look like. A custom separator for author does not make sense positionally but accepting a name, and defaulting it, does fit with what someone would expect. I removed the `_from_crate` suffix because it doesn't seem necessary. We don't have this kind of naming for the derive. I feel it cleans things up this way.
