Why not allow both styles? Is there any benefit to forcing one way or 
the other?

The problem is though, you'll forget whether the parameter is called 
"center", "position", "location" or "centre", and then have to look it 
up anyway. And that's for something simple like a sphere. Imagine you 
come to include something as horrendously complex as a cylinder or cone 
in your scene, what are the parameter names for the two end points? 
Personally I find it far easier to remember the order of parameters than 
the names.
