Its a different model really. NIF's have started to allow people to
re-implement almost anything a port driver can do, as well as things
they can't. Though, the question is more about technical debt at this
point.

For instance, if you had a situation that could be solved as a port
using the async thread pool, why would you want to re-implement that
as a NIF? NIF's are extremely awesome and its easy to assume they're
better for everything but there are definitely cases where a port
driver is a better fit.
