A queue-handler could have a set of criteria that, when satisfied, would result in an immediate drop or accept.

There's no difference between returning NF_ACCEPT or a new NF_CONTINUE.
Queueing happens outside of the ruleset context, so in either case the
packet would continue through the network stack directly, not after
the NFQUEUE rule.
