most of the cairo based renderers need no special code beside the surface 
instantiation, e.g. cairo_svg_surface_create() in plug-ins/cairo/diacairo.c

... and this is a derived class only overriding methods specific to SVG 
export. The other derived renderer is the shape export.

implmented by diasvg.py

If you disable all three SVG exporters there wont be anyone left, yes.

If I not already answered this above, I dont understand the question ;)

BTW: In your previous mail you added a patch to the SVG renderer, which was 
discussed and rejected in https://bugzilla.gnome.org/show_bug.cgi?id=655718
