Has Anyone Used Microsoft Graph Schema Extensions for Group Management?

I'm curious if anyone here has experience with implementing Microsoft Graph schema extensions to tag Entra ID groups with structured metadata. I'm not referring to custom security attributes, since those still don't support groups. I mean the actual Graph schema extensions, which provide a way to directly assign custom attributes to group objects in Entra without cluttering group names.

In my setup, I've configured it to help simplify naming conventions. Instead of cramming all the details into group names, like resource name, IAM role, environment, and team, I generate straightforward names like xyz-Azure-func-001 and use schema extensions to attach relevant metadata directly to the group.

For each group, I include attributes such as:
- resourceName: "myapp-prod-func"
- role: "Contributor"
- environment: "Production"
- serviceType: "FunctionApp"
- index: 001
- createdBy: "runbook"
- lifecycleStatus: "Active"

This data is written directly onto the group object using the Graph API, and the entire process is automated with Azure Automation runbooks that manage tasks from generating the next group index to assigning IAM roles. This method has vastly improved group governance and automation by decoupling group names from any role or resource changes, allowing for easier updates without needing to rename groups. Plus, it feeds data into Azure Tables or SQL for visualization in Power BI, making it easier to track group metrics.

Is anyone else adopting schema extensions for better group management and organization?
