Once a particular setting has been saved by the user (or by the application or by a plugin) then it has a value and the default value is never used again. The idea behind global settings is that we didn't want to store default values inline in C++ code (that would imply to rebuild the whole application just to fix a default value) and we wanted a way to override default values for the users by providing a (possibly customised) default settings file.
