Use case is to detect whether the browser claims to dispatch such
(trusted) events.
Currently
     if (element.onfoo) { ... }
is occasionally used for detecting support for some events, but that 
doesn't really work since not all events have onfoo event listeners.

(And note, DOM 3 Events isn't just trying to document what is currently
  supported.)
