you can easily still use external etcd if you really need to.

But in general k3s can be HA without issue and scaled just as well as vanilla k8s. The main advantage of it is that everything comes neatly packed into a single binary whereas the alternative would mean to have a multitude of services running for cluster provisioning.

Kubernetes in the end is basically an API server with multiple componets and k3s puts a nice bow around all of them.
