Add event initializer

[wherewhere]

When we initialize an object with event, we need to write

class A
{
    public event Action Event;
}

A a = new A();
a.Event += () => {};
a.Event += () => {};

But if we need to initialize someting in initializer, we have to write

class A
{
    public A Child { get; set; }
    public event Action Event;
}

A child = new A();
child.Event += () => {};
child.Event += () => {};

A host = new A
{
    Child = child
};
child.Event += () => {};
child.Event += () => {};

So if we have event initializer, we can write it like

class A
{
    public A Child { get; set; }
    public event Action Event;
}

A a = new A
{
    Child = new A
    {
        Event =
        {
            () => {},
            () => {}
        }
    },
    Event =
    {
        () => {},
        () => {}
    }
}

The event is like a delegate collection which both have Add method, so why not make an initializer for event like collection one? I know there should already have a proposal somewhere but I can't find it...
