It's irrelevant whether this is good programming style or not. It would=20
be nice if applications would unregister themselves before exiting, but=20
unregistering has to happen outside the application in any case because=20
applications will exit without unregistering for various reasons, e.g.=20
if they crash, or if they are killed, or because in some code path the=20
unregistering was forgotten.
