cc @dongjoon-hyun @cloud-fan - it'd be great if you get a chance to review this! I know it's a bit of a large change, but I tried to make it as isolated as possible and explain it well - let me know if I can be of additional help. (Also, a large part of the diff delta comes from the regenerated benchmark results AFAICT.)
