K3os vs RancherOS

I use RancherOS as server for some time without problems, but it looks like RancherOS will be replaced by k3os? Is RancherOS end of support?

I liked the RancherOS way (system-docker, all system services as container…), but k3os do it different with openrc and “nativ” services like udev?

Why k3os seems to be work different instead of services moved to containers? Wouldn’t it possible to use k3s(-server) as PID1 and automatic loaded services / pods for system services?
