It's irrelevant whether this is good programming style or not. It would 
be nice if applications would unregister themselves before exiting, but 
unregistering has to happen outside the application in any case because 
applications will exit without unregistering for various reasons, e.g. 
if they crash, or if they are killed, or because in some code path the 
unregistering was forgotten.
