You should make it as complicated as it needs to be, but no more. The first model nests one deep, while the second goes two levels deep, yet they both provide the same granularity for accessing the VFs, so I would go for the first. And I’m not sure that we will be able to get the “inherited” traits used in the second model implemented any time soon.
