Private Endpoint support in Front Door
Front Door is useful for private networking scenarios as well as public. For example we are beginning to use it as a routing for Blue/Green Deployments of our internal apps.
To keep the apps secure, we want to have a private traffic route into the Front Door and also out to the backends.
This could be by the new Private Endpoints. There is also a separate feature request on here for VNet support.

We make this work today by configuring the Azure Load Balancer to only accept calls from the known FrontDoor IPs. Would be much better to have a private endpoint, so we could be sure there is never a misconfiguration.
