Should we add information that replicas are ignored if > 1, IE Use of replicas within a spec file, will not cause a failure. As I understand it.

You are correct, so maybe we should use something else, e.g.:
| replicas | ✔️ (the actual replica count is ignored and set to 1) |

or via a footnote?

I like the way you wrote it here, rather then footnote.

@rhatdan Yes I agree. Footnotes are cumbersome for the reader. In any case, I wouldn't remove the supported sign because it might confuse users to think that podman will fail if the field is set
