 - **dynamic fleet orchestration**: So-called providers interact with multi-cluster solutions like Cluster API and dynamically start and stop reconciliation against clusters discovered through the provider.
 - **no fork, no go mod replace**: clean extension to [upstream controller-runtime](https://github.com/kubernetes-sigs/controller-runtime).
-- **universal**: Any kind of multi-cluster solution could theoretically be supported (kind, [cluster-api](https://github.com/kubernetes-sigs/cluster-api), [Gardener](https://gardener.cloud/) (tbd), [kcp](https://kcp.io), BYO). Cluster providers make the controller-runtime multi-cluster aware.

 - **seamless**: add multi-cluster support without compromising on single-cluster. Run in either mode without code changes to the reconcilers.
