Wouldn't be surprised if this goes through the same process Windows users did with WSL. Starting out with no systemd, to community-developed systemd-in-a-bottle setups, to proper systemd integration
OCI containers are supposed to be "one container, one PID": at the very least the container's server is PID1 (at times other processes may be spawned but typically the container's main process is going to be PID1).
Containerization is literally the antithesis of systemd.
