### 3.3 Automatic removal of delete markers with no other versions

When an object has only one version as a delete marker, the latter can be automatically removed after a certain number of days using the following configuration:

```
{
    "Rules": [
        {
            "ID": "Removing all delete markers",
            "Expiration": {

- The GA TokenRequest and TokenRequestProjection feature gates have been removed and are unconditionally enabled. Remove explicit use of those feature gates in CLI invocations. ([#97148](https://github.com/kubernetes/kubernetes/pull/97148),...
