I don't think it's a problem we use bootc for this but it's inconsistent with what we currently have. I personally prefer using bootc for this.

Yeah the reason that is is I didn't want to touch image-info things in this PR. We didn't add -testing to the image-info.json and I'm not sure if it's worth it? I was thinking once we're all deploying testing branches we can go back and make it consistent.
