Just my opinion, but most new releases, for any language, have very minimal impact on competitive programming. So it doesn't really matter if it's added to cf or not.
Arrays.sorton primitives now are guaranteed $$$O(nlog{n})$$$.source?
The documentation for OpenJDK 17 says 'This algorithm offers O(n log(n)) performance on all data sets'.
The documentation for OpenJDK 11 says 'This algorithm offers O(n log(n)) performance on many data sets'.
