 The `Exists` operator can be used on a NodePool to provide workload segregation across nodes.

-With the requirement on the NodePool, workloads can optionally specify a custom value as a required node affinity or node selector.  Karpenter will then label the nodes it launches for these pods which prevents `kube-scheduler` from scheduling conflicting pods to those nodes.  This provides a way to more dynamically isolate workloads without requiring a unique NodePool for each workload subset.
+With this requirement on the NodePool, workloads can specify the same key (e.g. `company.com/team`) with custom values (e.g. `team-a`, `team-b`, etc.) as a required `nodeAffinity` or `nodeSelector`. Karpenter will then apply the key/value pair to nodes it launches dynamically based on the pod's node requirements.

+If each set of pods that can schedule with this NodePool specifies this key in its `nodeAffinity` or `nodeSelector`, you can isolate pods onto different nodes based on their values.
