Comment(by azaozz):

 9952.4 is about the same as 9952.3 but it doesn't allow registering a
 widget that calls one of the old default widgets callbacks (not existing
 any more). Then it checks for already registered widget with the same id
 before registering new widget. This would stop registering widgets with
 conflicting id's too.
