Most of the graph theory functions have a bunch of options for the format of the output, I'd say this would follow that trend, taking the old behavior as default. > > Is there any other machinery you find missing or in need of attention? > > For now only a minor one: is it easy to draw a graph with LaTeX > formulas labeling edges?

This would involve making two separate graphics objects and figuring out how to add them together to get the right effect.
