Gerv, The Mapnik project currently leverages Cairo to output this SVG. There are a variety of limitations to this SVG output that make post-processing difficult, as you've noticed.

We have preliminary plans to write a custom SVG rendering backend for Mapnik in the future that will address things such as embedded fonts, selectable layers, etc. 

But things such as the road widths and font sizes are always going to be controlled by the styles used to render. User configurability of styles sent to Mapnik (by non-programmers) is something that a current Google Summer of Code project is looking into. See:
