The fact that EventRouter contains lot of Unity callbacks is not really a problem since those callbacks themselves only actually do something if something is subscribed to the related c# event in the first place (we check if the event is null before doing anything). The Unity callback itself is not really a concern.
However, the EventRouter does indeed have a problem with Animator, because the presence of OnAnimatorMove alone makes Animator not work correctly. I have fixed this now by moving OnAnimatorMove callbacks to a separate monobehaviour which is added automatically only when an AnimatorMove event is actually being used/requested by some node.
I am attaching for you here the fix, which will of course also be part of the next version update.
