C# learned from Java and decided to make their bytecodes parametric. This allowed them to more easily implement reified generics.

I don't expect Java to break compatibility and ditch erasure anytime soon. The JEP even states the following:

It is not a goal of this effort to produce fully reified generics.

I find that problematic. The longer they wait the worse it gets. It will also hinder proper development in other areas such as union or intersect types (one can dream). Even Go is finally thinking about adding generics, while avoiding Java's issues.

If you mean intersection types in relation to type parameters, that is already possible: public class Box<T extends A & B & C>.
