Honestly, I'm pretty damn impressed with how Freerouting autorouted these new boards
One thing in particular strikes me - the "Y" at the bottom-left. It put two of the traces at 45-degree offsets to slightly shorten the length of the trace feeding them and the overall trace length on the board.
It really doesn't just optimize for vias.
