This is exactly what newer versions of Java allow you to do. The problem is, nobody does it. I really like C# as a language, its better than Java in nearly every way. But this is a rare case where C# is implementing a feature Java has had for a very long time. And just like in Java, I don't think it will have the impact advertised.

The trouble comes in your dependencies when you don't know what they're reflecting upon or what features they're using that aren't supported.
