Getting someone up and running with a flake.nix with a defined devShell is just as simple and probably requires less knowledge since it's not another tool bolted on. Making the env and CI reproducible should be seen more like a good stepping stone and you can take the next leap when ready since it can all happen in the same flake file rather than a separate YAML one. The world is your oyster approach is skipping Docker and just running Nix on the server without the overhead of containers.
