Well, that's when you come from the GRASS perspective with a very 
specific meaning for 'centroids'. I think for most users centroids are 
the center of mass. So, I'm not sure that this will really be an issue 
of great confusion.

But I won't make an issue out of this. v.centerpoints is already a nice 
solution and I think it should be moved to trunk, although I've stumbled 
on some issues, but I'll file bug reports on those.
