Config.AllowAclUrlReservation = false; causes ObjectDisposedException

[c0nnex]

ServiceStack 6.4.0
Selfhosted App derived from AppSelfHostBase with
Config.AllowAclUrlReservation = false
to enable showing a custom information to the user why app requests UAC now.

Second call of ServiceStack.Start(listenOn) after manually calling HttpListenerBase.AddUrlReservationToAcl(listenOn); throws a ObjectDisposed-Exception on
ServiceStack.Host.HttpListener.HttpListenerBase.Listener

Workaround:

internal void ResetListener() {
            if (Listener != null)
            {
                if (Listener.IsListening)
                    Listener.Stop();
                Listener = null;
            }
        }

to enfore creation of a new listener. Very ugly.
How about providing a Callback action to Host prior to doing the AddUrlReservationToAcl to enable showing of a custom information.
Most users will click cancel if an app requests admin previleges and they do not know why (which is generally what i advise to them as well. Any app requesting admin priv, and you have no idea why? deny it)
