As per the subject line I often notice that what comes out of inkscape and other svg capable editors uses paths to represent circles and other simple shapes. I suppose this is for some reason of code optimization (i.e code optimization in the editor not in the output SVG). Can anyone shed any light on this?

Yes, in vector graphics Bézier curves are a wonderful generalized way to create shapes. Once you have the code to do them, all the other shapes can just use the same rendering code if you represent them the same way.
The way the SVG specification is written, I'm not surprised that other SVG editors also use paths for representing basic geometrical shapes.

If you use Inkscape's ellipse tool, the SVG representation will use a <circle> element if it is truly a circle, an <ellipse> element if it is an ellipse, and a <path> element if it is pie shape or a partial circle/ellipse. The SVG 2 standard does prescribe a standard way to decompose a circle and an ellipse into paths, mostly for positioning markers, dashes and text on a path.
