Description

I understand that https://github.com/hashicorp/terraform-provider-azurerm/issues/27109 was closed as unplanned as defaultIngressControllerType was a preview functionality at that point of time.

With the ManagedClusterIngressProfileNginx configuration being GA in 2025-02-01, and https://github.com/hashicorp/terraform-provider-azurerm/pull/29761 merged in, could the request for defaultIngressControllerType be reconsidered for support please?
