    <!-- This dependency can be considered optional; omitting it during runtime will most likely
      not cause any issues. However, it is not declared with `<optional>true</optional>` because
      that can lead to cryptic compiler warnings for consumers, and to be on the safe side in case
      there are actually issues which could occur when the dependency is missing at runtime.
