Agreed, alone this will help with a lot with performance with games with still solid objects.
As well, this works perfectly with my complex sprite map set up using lists.
But because of how hitbox merging works, raycasts had to be taken out of the behavior list. So simple spritemapping with Raycast are out for the time being. But this type of sprite mapping is one of the main reasons for this feature, so look forward to more updates.
