No.  The bootstrapping node will writes for its new range while
bootstrapping as consistency optimization (more or less), but does not
contribute to the replication factor or consistency level; all of the
original replicas for that range still receive writes, serve reads, and are
the nodes that count for consistency level.  Basically, the bootstrapping
node has no effect on the existing replicas in terms of RF or CL until the
bootstrap completes.
