docs: Determine the index of the getCursor to use based on the classifications defined
  for the ConsumerSet that a consumer belongs to. If SIB is not registered with
  XD and no classification is being performed then the default index is returned
  
  Delegates to the consumerSet if non-null, otherwise returns the
  default zeroth index.
