Motivation for this change

Since I can no longer maintain and oversee this package, I hereby drop my own maintainership for this package.

However, since to my understanding (after reading CONTRIBUTING.md and the manual) a package must have at least a maintainer, I'm not sure what to do. So I opened this PR in hope for someone to see this and decide to take the helm.
