We will eventually start emitting and dispatching custom notifications from plugins just like we dispatch internal notifications. In order to get reasonable error messages we need to make sure that the topics plugins are asking for were correctly registered. When doing this we don't really care about whether the plugin that registered the notification is still alive or not (it might have died, but subscribers should stay up and running), so we keep a list of all topics attached to the `struct plugins` which gathers global plugin information.
