 Peer _management_ is a closely related concept and refers to the set of actions a client MAY choose to perform based on its knowledge of its connected peers,
 e.g. triggering reconnects/disconnects, keeping certain connections alive, etc.

 The peer store SHOULD be an in-memory data structure where information about discovered or configured peers are stored.
