I tend to disagree, see below

If they are the same for this user, They will just use one or the other (most likely end() ). But for others, they can put any logic they want on 2 'event-handlers' so..

Could be, but that makes it more difficult to implement. You can get that functionality by declaring 2 event-handlers as mentioned above.... I would not make it overly complicate. But if kind of hierarchical events are introduced, that would be fine to. In that case we agree and is it less complex/difficult than we thought.
