Well, using the same index seemed to comfortably explain that the size
of the individual adjacency mappings depends on the number of nodes in
V. But for that to really make sense there'd need to be a different
indexes for U/V, which I now see wasn't the case case before
either. As currently used they'll be the same anyway...
