When referring to vague terms as DIK route, chick route, and neutral route, you are prone to make mistakes in your arguments. There is indeed one scene with Maya that you will only unlock if you have the right amount of DIK points. If they are too high or too low, you will miss it. In both my Massive DIK play and my Massive Chick play, I missed that scene. And while it may be possible to obtain it being on DIK or Chick routes, you must meet a specific requirement (I don't know exactly the amount of points, but it must be in the walkthrough), so you could say that it is in a more or less neutral play that you can obtain that scene. If she regards you as being too DIK or too Chick, Maya will not go further with you on the night after the party.
In my interpretation, she doesn't want to (at the time) engage in some sort of relationship with a guy that is either a jerk or a saint. So, I perceive her and Josy to be more neutral than chick LIs. But that is my opinion.
