Let's be clear - you're saying there's nothing wrong with the registry, it's a great aspect of the architecture of Windows, and it doesn't result in applications being tightly bound, interconnected, difficult to uninstall and that bits and pieces are never left in the registry, that the registry does not contain orphaned configuration elements, it does not slow down Windows and in the past 10 years it has never needed "cleaning/defragging" as you call it? And you advocate for modern applications to use the registry for their configuration?
