It appears that docker cli will also eventually remove the short option for help. Their reasoning for it is to avoid conflicts with args (eg hostname '-h') in certain subcommands.[0][1]

But I don't see why they couldn't leave the base command's short option alone-- the user intent of a bare "docker -h" (or "podman -h") seems obvious.
