A lookup in an empty list/tree would of course equal a single pointer
comparison, so if someone is not using the feature, there's no
additional cost.
And since the lookup happens after the ordinary state lookup (and only
if that fails), the cost occurs only per connection, not per packet.
Compare to the per packet cost of forwarding the connection through
userland...
