Good post, solid feature coverage and the YAML examples are really practical. Two things need a pass before we publish: the draft talks about "customers," "users," and "operators" instead of talking directly to the reader ("you"), and there are a few phrases we don't use ("deep dive," "it is critical to note that," "The key takeaway is," "leveraging"). Inline comments have the specifics.

A profile is a set of one or more in-tree scheduling plugins and configurations that dictate how to schedule a pod. AKS supports 18 in-tree Kubernetes [scheduling plugins][supported-in-tree-scheduling-plugins].

i added a callout to the multiple scheduler use cases in the last part of this section

website/blog/2026-04-06-aks-config-scheduler-profiles-preview/index.md
| Configurable Scheduler Profile | NodeResourcesFit: MostAllocated | Maximize consolidation / bin‑packing | Maximum node utilization, highest cost reduction potential |
| Configurable Scheduler Profile | NodeResourcesFit: RequestedToCapacityRatio | Targeted utilization with headroom | ✅ **Recommended strategy** Increased utilization with stronger control over consolidation and burst headroom than `MostAllocated` |

this is and increasing gpu utilization examples aren't "use cases"; they are different implementations of one "use case" using two different resources.

I understand what you are thinking but I don't think it is required
