The one exception to this is if you’re using your homelab to learn kubernetes.
That was the only time I used K8s and k3s on my homelab.
And for anything that I do want to set up in a HA/cattle kind of way, I use Docker Swarm, as it feels like a more comfortable extension of docker compose.
I have other means to detect forced entry. The door and window sensors and motion sensors that require an alarm code be entered for example.
