Before C# 14, there were just a few rare erasure conflicts in C#, like when u define overloads differing only by `ref` /`out`. With C# 14 extensions, we are one step closer to Java, with its stupid "have the same erasure" conflicts

Is `internal interface I` implementation in `public class C : I` is a part of the public API surface? Can u erase the `: I` without breaking the consumers? Given `public interface IPublic<T>`, what about `public class C : IPublic<I>`?
