Yes, a custom, better SVG renderer in Mapnik is planned. We have recently made major steps on fundamentals for this renderer, notably Mapnik master now has a solid geometry framework for clipping, simplifying, smoothing, and serializing as SVG. We've had a stub in place for custom SVG renderer for a while, but the lack of these things held it back. The next steps is to return to updating it and then adding grouped layer support.
