Looks good! I left a few more thoughts on how we might generalize things more, but none of them should be blocking.

Not for this PR, but will we also want a fn register_event_key(&self, &mut World) -> EventKey, similar to ReflectComponent::register_component?
I think that would make it just possible to construct a completely dynamic observer using Observer::with_dynamic_runner, Observer::with_event_key, and ReflectFromPtr::from_ptr. And the fact that everything would be possible might discourage certain reviewers from trying to overgeneralize the convenience methods :).
