I'm not aware of any specific design reason, but if you want to put a REJECT at the bottom of the list, you can.

REJECT is a special target, like custom chain and therefore you probably cannot use it that way, however I am not expert in iptables queue. You need to drop packet and manually respond with proper ICMP message to mimic a REJECT target.

Another question about the function below related to libnetfilter_queue:
int nfq_set_queue_maxlen (struct nfq_q_handle * qh,u_int32_t queuelen)
How much can i take "queuelen" big (how many packets)?
Do we have to consider memory size consideration?
and another questions step by step after the answers
