Add Assert.RaisesAny and Assert.RaisesAnyAsync non-generic for EventArgs

I know there's public static RaisedEvent<T> Raises<T>(...) in EventAsserts.cs but that only works for the EventHandler<TEventArgs>, AFAIK.
My event is of plain EventHandler type and I'd like to verify it was raised.
I ended up implementing it a bit dummy way on my own, here's the code:

    public class Testing
    {
        public static void RaisesEvent(
            Action<EventHandler> attach,
            Action<EventHandler> detach,
            Action testCode)
        {
            bool isEventRaised = false;
            var eventHandler = new EventHandler(delegate
            {
                isEventRaised = true;
            });

            attach(eventHandler);
            testCode();
            detach(eventHandler);

            Assert.True(isEventRaised);
        }
    }

Is there a way to achieve that using a standard xunit tools?
If not, would you consider adding it?
