Because IMnsHO the API of QSettings is useful to talk to a settings 
backend, but not so useful as an API for an application to talk about 
its specific settings. Do you really want to use strings as keys and 
cast to and from QVariants throughout your code? I don't. Just like many 
other posters, I much prefer an API where the settings are explicitly 
coded and type safe. That is: there are explicit getters, setters and 
where needed, signals for each of them.
