 For the external controller to patch the `.status.nominatedClusterNames` field there are 2 options:
 * Use the `kueue-admission` field manager, because the kueue-admission field manager is responsible for managing updates to the `.status.nominatedClusterNames` field.
-* [Enable `WorkloadRequestUseMergePatch` feature gate](docs/concepts/workload#workload-updates-by-kueue) that drops the `kueue-admission` field manager from the `.status.nominatedClusterNames`.
 
 Without this, the Kueue is not able to admit the MultiKueue workloads.

-By default Workload status updates are performed by Kueue using the [Server-Side Apply (SSA)](https://kubernetes.io/docs/reference/using-api/server-side-apply/). 
-
-However due to the limitations of SSA ([missing support for duplicated key/value pairs](https://github.com/kubernetes/kubernetes/issues/113482)) we also offer to enable updating the Workload status
-with Merge Patches, by enabling the `WorkloadRequestUseMergePatch` feature gate. 
-
-In particular, this allows users of Kueue to handle the following two issues:
-- [Add option to disable strict pod spec validation](https://github.com/kubernetes-sigs/kueue/issues/3540) 
-Switching from ServerSideApply to Merge Patch allows partial updates without requiring the entire resource specification.
-This can bypass the strict validation rules causing issues with duplicated environment variables, aligning Kueue's behavior more closely with plain Kubernetes
-- [MultiKueue: remove the limitation that the external dispatches need to use kueue-admission field manager ](https://github.com/kubernetes-sigs/kueue/issues/6185)
-Using ServerSideApply blocked the ability for Workload Status to be modified from external controllers.
-Once the field e.g. `.status.nominatedClusterNames` was modified and owned by the controller (regardless if Kueue or external one) it can not be modified or cleared by the other.
-This effectively prevent External Dispatching mechanism to work properly in multi cluster enviroment.
