> You don't have to fully switch

Having a heterogenous fleet can be annoying though, some Podman-only config values[1] stop Docker dead in its tracks because it hates unknown fields.

1. It was a while back, and I can't remember what specific field it was, but it had to do with namespacing and/or (sub)UID mapping.

I can imagine that but I don't have those issues with the default config. So it allows using docker compose with podman directly.

On the other hand I could see it being hard for people to only install the cli part of docker. Luckily on arch that was simple due to how it's packaged.
