[Podman] Why 'podman-docker' package conflicts with 'docker'

Hi, I have a question, why does 'podman-docker' package conflicts with docker ? I tried installing both at the same time but faced conflict. Is the conflict is by design? I have seen specification of podman-docker in the following link https://archlinux.org/packages/community/x86_64/podman-docker/ It says it conflicts with docker, but I want to know the reason for such spec. I would like to know why 'podman-docker' and 'docker' can't coexist? It would be really helpful. Regards Nishant Nayan
