Explicit helps when you have all the raw objects and have to be explicit in how you use them, but when calling functions that accept a base class or using an object factory, it gets more complex.

You wouldn't use it in that circumstance. You'd use it when you needed
it - i.e. when you desired the behavior it provides.

It neatly solves the problem of

    class A
    {
        /* provide opCmp */
    }
    class B : A {}
    class C : A {}

    B b = new B;
    C c = new C;
    if (b < c) ...

doing the wrong thing.
