Well its public so who knows in what other package is using it. And it’s static, so who know what kind if monster is calling it from some inapropriate place. I have seen static methods being called from translation/localization files, because “it works”.
IntelliJ finds most uses in my experience unless you’re doing something weird with reflection or similar. And if it’s a public facing API only used by the library’s consumers…– it should be used in tests at the very least! Especially if it’s prone to regressions like the comment suggests
