I would agree if you're explicitly talking about 2-space or 3-space.  
But if you're dealing with higher-order geometries, then a coordinate 
becomes an N-vector and now it starts to feel more like a list than a 
tuple.

I can't put any rigorous argument behind that, it's just what (to me) 
feels right.
