As I pointed out in a different comment, even IBM have to maintain a GitHub Actions runner fork with s390x support because upstream just cannot even be bothered to accept the relevant patches: https://github.com/uweigand/runner

If IBM cannot get Microsoft to work with them on something so small but impactful, there's no chance we can.

And it's in the hands of a for-profit company pushing LLM nonsense. That should be alarming! Let's instead encourage people to use platforms managed by non-profits.
