+ * pass specific references through dependency injection. All references on this struct
+ * *should* be explicitly checked for availability as this struct does not guarantee anything.
+ *
+ * \note Dereferencing members of this struct should be deferred. If you are a user of this
+ * class, keep a reference to this mediator instead of just picking references from it when you
+ * receive an instance.
+ *
+ * \warning This class should never be directly accessible from the API
