I too have learnt to like systemd.
But what is the relevance here? In what way is it a replacement for docker?

These are container tools offered by systemd.
The problem is that the tooling for creating, importing, and managing images is not as good with systemd vs Podman/Docker. There's also no clear path to import images from the Docker ecosystem, at least as far as user experience goes. I know how to do it, but the number of extra steps involved always drives me back to Podman.
I don't really find them that bad but I'm still going to maintain my "different strokes for different folks" position. Might be bad for you and good for others. More options isn't a bad thing
The systemd suite of container tools treat containers like mini VMs and expect a full init system. They are not designed for ephemeral single-process app containers like docker containers.
I think you only looked at nspawns. Check out the other two
podman is supposedly a replacement for docker.
There's plenty of container technologies and I'd be happy to see more of them used. Podman isn't for me, but it is a great option for others. Regardless, I think it is relatively unknown that systemd can be used for creating containers.
