I wouldn't say they are "not compatible", since the move that maximizes score is always in the top class (win>draw>loss) for any setting of komi. You probably mean it in a practical sense, in that MCTS engines are stronger when maximizing win probability.
I am more interested in attempting to maximize score, even if the engine is significantly weaker. Of course this is not what most people want, so I understand I am looking for something unusual.
