When using small mezzanine connectors it is good practice to route unused pins to dummy tracks with vias close to the unused pads.

That sounds interesting, but could you explain why? Does this improve mechanical robustness? How?

Any copper track to a solder pad simply increases adhesive power between copper layer and substrate. This is very important in case of poor soldering which usually happens during manual assembly.
