Just curious: Where did you heard about that Dennis moved to Apple :) ? Some clarification: * the process of the route finding is done by Dijkstra or A* or with a preprocessing (CH) * valhalla does not use CH to my knowledge * route optimization requires a completely different technique and valhalla does not do this > "The OP (Mapzen's Valhalla) appears to have a similar approach as OSRM" no :) ! OSRM is limited to CH (really fast) and valhalla is limited to Dijkstra/A* (really flexible).
