1. Most of the issues I had that forced me to adapt a docker-compose was because I was using podman rootless and most people build docker-compose file with docker running as root in mind. mostly to have access to privileged ports. I guess running podman under root would have solved this but one of the reason I switched to podman in the beginning was for the rootless capability. In a way this wasn't much different than modifying a deployment to work with docker in rootless mode.

2. part of the appeal of using podman is its compatibility with kubernetes yaml file so you tend to quickly switch away from docker-compose anyway. Also for self hosting, the systemd approach was more elegant, even before the quadlets support.

3. One would argue that docker-compose != docker/moby engine.

4. docker-compose has introduced breaking changes in its history which meant adapting your compose file or add flags at runtime such as `docker-compose disable-v2`
