>
> 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.
