Automatic cordon/drain when deleting node pools

Feedback

When deleting a node pool, AKS automatically performs cordon and drain. This has been confirmed by the AKS team Azure/AKS#3996 (comment). However, the documentation states that it does not. This is a follow up on #117049, in which this information was only corrected in the Azure CLI tab but not in the Azure PowerShell tab. In addition, the same piece of information is present on this page Delete an Azure Kubernetes Service (AKS) node pool and possibly elsewhere.

As an engineer working with AKS, lots of the decisions around the setup and automation were based on the official documentation. Investing a considerable amount of effort based on wrong information can be quite frustrating. Documenting the exact opposite behavior of a feature is probably not a good idea, especially for such a high quality product like AKS. Therefore, I kindly ask you to clarify and document the behavior of AKS around deleting node pools properly (on all pages/occurrences).
