I'm not sure what you are referring to.  Everywhere in the spec
where it says "rejoin the network", it always say delete
init_neighbor_list first!  So, it cannot do a "rejoin based
on the init neighbors".

A regular node is either JOINing the network (when it does
not have an init_neighbor_list file) or participating in the
network (when it has an init_neighbor_list file).  It cannot
do both.
