 - **Infrastructure provider complexity**: requires infrastructure providers to implement and maintain an InfrastructureMachinePool type.
 - **Less per-machine granularity**: you cannot configure each node individually; the pool defines a shared template.

   > **Example**: AWS allows `AWSMachinepool.spec.mixedInstancesPolicy.instancesDistribution` while Azure allows `AzureMachinePool.spec.orchestrationMode`.
 - **Complex reconciliation**: node-to-providerID matching introduces edge cases (delays, inconsistent states).
 - **Draining**: The cloud resources for MachinePool may not necessarily support draining of Kubernetes worker nodes. For example, with an AWSMachinePool, AWS would normally terminate instances as quickly as possible. To solve this, tools like `aws-node-termination-handler` combined with ASG lifecycle hooks (defined in `AWSMachine.spec.lifecycleHooks`) must be installed, and is not a built-in feature of the infrastructure provider (CAPA in this example).

+Providers may support the deletion of single machine pool `Machine` objects. That allows, for example, using `MachineHealthCheck` to remediate machines that became unhealthy.
