And there you have it: QFormBuilder mustn't save non-STORED properties. 
If it does, it's a bug. And if we have some widget with interlinked 
properties that are not clearly marked as non-STORED, or refactored to 
be grouped together in a proper datatype, that's another bug.

Then I fail to see the usefulness of QFormBuilder apart from being minor 
convenience, and therefore it should be overall deprecated.
