Protected defeats the purpose of it because.

A inherits B and B inherits C.

A only accepts B to manipulate the field of A and not C.

With protected C can access it. With this fixed to have same 
behavior as other languages then C will not be able to.

D didn’t implement friends because you can access private fields 
within the same module, but it’s not possible in this scenario 
and that’s a bug.

If it shouldn’t be possible then D does need to implement friends.
