REVISION SUMMARY
  config suboptions are separated by ":" (see the path one for example). So we
  dont want to confuse these config with actual extensions.
  
  We don't have extensions sub option yet, but I am about to introduce one for
  making sure an extensions can load. So lets level the floor first.
