Do they? I thought this is more issue on the source code side, rather than implementation: this is actually my pet-peeves, that most SVG *authoring tools* never output circular arcs and always use cubic béziers approximations instead. So we nearly ever see real circles or their segments, even though authors use them in their designs all the time.
