> The leader will happily accept connections from learners that have the same server id (i.e., due to misconfiguration). This can lead to various issues including non-unique session_ids being generated by these servers.
> The leader can enforce that all learners come in with unique server IDs; if a learner attempts to connect with an id that is already in use, it should be denied.
