The "size" attribute was removed along with the unified primitive syntax. It's no longer meaningful for most primitives, but for box it might be convenient:
It does seem clumsy to have to write out length=10, height=2, width=10. While one might argue that (10,2,10) are a bit too much like positional arguments, in fact mentally one does want to associate them with something like (x,y,z), so I think this is desirable for boxes.
