As long as the adapter is trivial, it can be handled with __getattr__
and __setattr__ instead of a bunch of individual properties. That
also allows you to deal with evolution of the IUserSettings schema
Another thing this buys you is that you're only dealing with
application-level values; the widget implementations become completely
irrelevant. Many widgets use more than one control these days; that's
something you don't need to deal with this way.

Sounds possible, but fragile. It should also be possible to
pre-populate the form's adapters dictionary (self.adapters).
