Review Comment:
There is not particular reason, I guess. @hachikuji The reason I kept it
like this is that we will need to fan out any way with the new controller as we
will have multiple event loops. I suppose that we could say that this is an
internal implementation details so not exposing it in the interface would make
sense. What do you think?
