+      Runs unit tests for an OpenStack Python project under the CPython
+      version 3 releases designated for testing in the Wallaby release
+      on top of ARM64 architecture. This currently runs only a limited
+      test set and supplements the python3-wallaby-jobs. And it should
+      not be run instead of the default!
