Azurerm machine learning managed network outbounds support

Azurerm does support managed_network for Azure Machine Learning workspace (azurerm_machine_learning_workspace - support for managed_network.isolation_mode by katbyte · Pull Request #24951 · hashicorp/terraform-provider-azurerm · GitHub) , but only isolation mode block was added. It also needs outbound rules block.

When will the support for outbound rules be released ?

I know azapi provider supports this, but if azurerm can release outbound rules for managed network soon, we can delay our implementation till then. Please let me know.
