If a lagged node is not aware of newly added node(s), it simply cannot communicate with them. When it suspects its own eviction, it inspects certificates in them, would find itself still among consenter set. And if the leader happens to be among those new nodes, we have a deadlock. To break this, when a node suspects its own eviction, it also triggers a catchup to actually pull blocks and commit them, so that it can eventually recognizes new nodes.
