It's cool but also not as revolutionary as you make it sound. You can already install Podman, Orbstack or Colima right? Not sure which open-source framework they are using, but to me it seems like an OS-level integration of one of these tools. That's definitely a big win and will make things easier for developers, but I'm not sure if it's a gamechanger.
All those tools use a Linux VM (whether managed by Qemu or VZ) to run the actual containers, though, which comes with significant overhead. Native support for running containers -- with no need for a VM -- would be huge.
Still needs a VM. It'll be running more VMs than something like orbstack, which I believe runs just one for the docker implementation. Whether that means better or worse performance we'll find out.
