Why Do I need to redeclare type constraint in generic subclass

Question

Recently I tried to create a generic subclass by implementing a generic interface.

public interface IModule where T : DataBean { ..... }
public class Mo

Standard C# team wisdom. Declarations should be self-documenting. And most of all, a change in one type declaration should not alter the behavior of an unrelated other type without generating a diagnostic. The -100 points principle put into design is another take on that.
