Currently, a peer leaving the network does it without giving notice. In that sense, departures are equivalent to crashes. Nevertheless, if enough time is given, it could try to patch the network, i.e., not being as disruptive as it is currently by attempting connections from it inview to its outview (eg A-> B -> C, B leaves but first acts as a bridge to connect A to C, it becomes A -> C )
