- Don't enclose each argument in parentheses (why it's like that in References?)
- Config options should not have all contents marked as optional. If option is specified in config and is empty, it indeed set and has content (empty string, which will be interpreted as boolean false or number 0).
- Boolean config options do not "enable or disable". Generally, option just enables something (when it's set to non-false).
