• Should `ConfigManagingActor` send an empty `dict` on file deletion? #563

Right now the ConfigManagingActor is monitoring for delete events, but ignoring them, which doesn't seem very reasonable.

I guess if a config file was removed we could signal that by sending either an empty dict or None. If we really want to ignore deletions, then maybe we shouldn't monitor for create and delete events.
