To confirm, you're not passing python_settings here like you are in line 704 because we intend to pass empty settings since they weren't explicitly specified for self.naming.proto_package version?

We want to set empty settings against self.naming.proto_package if the key is not already set in line 704 which happens only when someone has an incorrect library_settings.version configured in their service yaml. We're doing this so our generator doesn't if it fails to find the settings that it's looking for.
