Sludge build up in both anaerobic and aerobic septic systems is proven fact and the systems fail over time.
Any cracks that may carry away the water from the waste within a lava rock cesspool is still subject to the continued biological environment it was initially dumped in and would continue within an aerobic environment until it became leached as water into the rock where any further contaminates would be broken down. So it's still spread out and still subject to all the previous aerobic bacteria and insect conditions.
Obviously right next to the ocean this doesn't work but further back from the ocean it works perfectly.
ETA in heavy population density areas the lava rock cesspool may not be as safe merely because such an area can become too saturated... maybe.
On one acre parcels or greater, it's highly unlikely lava cesspools would ever pose a problem and would more likely be better than septic systems.
