Possibly, but that isn't the issue. When they do have to be changed,
they have to be changed all at once. So either we have two mechanisms
for applying preferences, which is going to be confusing, or we have to
stick with the one mechanism.

Also, rather a lot of these changes take several seconds to apply and
involve redrawing the screen. E.g. desktop changes. That won't be
pleasant if it happens every time a widget is changed and loses focus.
