Review Comment:
I'm not really a fan of these if we're not actually doing anything (or just
proxying info) but I can put it back in. In general I think `EVENT` is more
meaningful when we've made some kind of decision based on data (e.g. when we
decide we need to apply backpressure) or an external signal.
