You can always call .rdd.top(n) of course. Although it's slightly clunky, you can also .orderBy($"value".desc).take(n). Maybe there's an easier way.
I don't think if there's a strong reason other than it wasn't worth it to write this and many other utility wrappers that a) already exist on the underlying RDD API if you want them, and b) have a DataFrame-like counterpart already that doesn't really need wrapping in a different API.
