Your assessments are pretty dead on. geom_fox from what I understood
was more of a proof of concept, and geom_multipath is the 'real deal'.
I played with both, and geom_multipath does well, whereas geom_fox did
have some shortcomings.
From my (maybe limited) experience, you should be able to use
geom_multipath without much issue.
