`directories-next` was created because `directories` was not maintained
at the time. However, `directories` has gotten active maintainership
since, and it has received more updates than `directories-next`.
`directories` also has more recent downloads than its `next`
counterpart, so it might make sense to switch to it, to avoid
unnecessary duplicate dependencies, where a project depends transitively
on both `directories` and `directories-next`.
The main question is whether we depend on any specific behavior from
`directories-next`.
