If I follow correctly, instead of v.to.rast, you need to interpolate a
raster DEM from the points. v.surf.rst produces nice results, but
there are other interpolation modules as well in the raster category.

If a polygon has no other touching it, it should have 2 nodes and at
least 2 verticies.
When polygons touch other polygons, topology comes into play. So
when polygon B is adjacent to, and touching polygon A, that makes a
node because it is a shared line segment between polygon A and B.
If the bridge and tunnel are valid route options, can you remove the
node and make them topologically incorrect? Meaning, crossing lines
with no node intersection so there is no option to turn. I'm not sure
if module needs topologically correct lines/network.
