add event after river item has been added

As discussed with hellekin

Would this just be something like:

if(elgg_trigger_event('create', 'river_item', $item)) {
    return true;
} else {
    $item->delete();
    return false;
}

I'm not a big fan of deleting something after it is created. I think that's a bad pattern. In general there should be a hook before something is created and an event after. If someone wants to prevent something use the hook. The event should be more of a "hey, this has happened". Otherwise, you introduce nasty plugin order dependencies (notifications sent out before an object is deleted).

Indeed. That makes sense as a rule of thumb. What would returning false from a create event then indicate?

stops any other event handler from running. not sure that is really needed or a good idea

No reason this can't wait until the 1.8.1 release
