- [x] whatsnew entry

Thanks for the PR - this will also need a whatsnew since its an API change. Think this needs abit of discussion before merging - there are lots of other methods this could be applied to. Doesn't make sense for the API to just support value_counts > Think this needs abit of discussion before merging - there are lots of other methods this could be applied to.
