I need these reviewed so I can finish the remaining backports. Downstreams never kept up with the incremental changes on main so they have PRs that conflate these changes. e.g., see opensearch-project/ml-commons#901 (comment)

@nknize I just wonder if eventually all Strings related methods will refactor to core lib, or if they are not refactored now, they will keep staying in their original library for a while?
