You could have looked at the actual commit, which contains the change log,
which says

- wait_for_any_job: check for any terminated procsubs as well as any
    terminated background jobs

wait_for_any_job is the function that backs `wait -n' without arguments.

Thanks for the clarification.

$ wait -n > >( cat )
would hang, in the event that there are no other un-waited-for child
processes, right?

Yes, it will wait for the next job or procsub to terminate.
