There's two cases where you'll see pragmatic wrapping:

1. Higher order usage. When functions would really benefit from being used in a higher order way, passed around as values, you'll see some of the Java methods wrapped so they can more easily be used as such, since you can't use Java methods in a higher order way. This would count as "can do it better", and it's the case for clojure.string.

2. For portability with Clojurescript. This is a more recent thing, but as Clojurescript usage grows, and code reuse between backed and frontend more common, there are certain basic methods Java interop was totally fine with that now benefits from being wrapped. This is the case for clojure.math.
