Interface inheritance - extend/implement only directly implemented interfaces

[zolakt]

I know the title is weird, but I don't know how to describe it better.
Here is a simple example:

This C# code:

public interface A { }

public interface B : A { }

public interface C : B { }

public interface D { }

public class MyClass : C, D { }

Will generate this TS:

export interface A { }

export interface B extends A { }

export interface C extends A, B { } // A is redundant

export interface D { }

export class MyClass implements A, B, C, D { } // A and B are redundant

So when you inherit an interface, it explicitly extends all the interfaces in the tree, instead only the directly extended ones.
Similar when a class implements an interface, it explicitly implements the whole interface tree.

I know it's not a function issue, but it's needless redundancy. I have long inheritance chains, and when I add something in the middle I need to update a whole bunch of classes. Does anyone have an idea how to get rid of the redundancy?

So just to be clear, the output I'm looking for is:

export interface A { }

export interface B extends A { }

export interface C extends B { }

export interface D { }

export class MyClass implements C, D { }
