No, I've manipulated shapefiles in ArcView with various layer types. 
One of the benefits of a layer is that it might be point, line, or 
polygon.  One of the drawbacks is that, to establish and display a 
centroid of a polygon, you have to add a point layer in the ESRI world, 
while you can add a centroid as a metadata element in some of the others.

I'll be awaiting developments.
