That is just the worst problem. Your system doesn't uniquely identify any arc. For every start, center, end points there are a pair of arcs that share the points. This is why we have G2/G3. If you don't have a normal vector you can't say which way is clockwise, so G2/G3 don't make sense. This is also a problem you get when you specify the arbitrary plane with three points, as was proposed by Ian M. The correct solution is probably to specify the plane's normal vector. While it's entirely possible to do, I doubt anyone would ever use this feature if someone did the work to implement it.
