* Registries backed by the generic Store's `Update` implementation support delete-on-update, which allows resources to be automatically deleted during an update provided: ([#48065](https://github.com/kubernetes/kubernetes/pull/48065), [@ironcladlou](https://github.com/ironcladlou))
        * Garbage collection is enabled for the Store
        * The resource being updated has no finalizers

And it will work and will be useful **during development**.

But if your connection to the server is lost, the **running process** will probably die.

And if the server is restarted (for example after updates, or migrations from the cloud provider) you probably **won't notice it**. And because of that, you won't even know that you have to restart the process manually. So, your API will just stay dead. 😱
