Gradle introduced a lot of breaking changes in version 5 (and subsequent versions as well) and I stumble across old, unmaintained code on github from time to time that requires gradle version 4 to build. So IMHO this package isn't "unneeded". Also not sure why it bothers you so much you want it deleted.
