Not included here:
 Action Descriptor parameter metadata needs to be designed. 
 BindNever and bindRequiredAttributes.
 FromPath,FormData, FromRouteData attributes 
 ActionSelection has a workaround to make it work with new binding world.


yes, if we are unable to select a formatter (lets say the input content type was not supported) . 
The formatter can totally return a null model, for example its a post with empty data which is a perfectly valid scenario.
