This is related to Issue 2538:

The spec has more information on interfaces here
https://dlang.org/spec/interface.html

And here is a simpler example:

interface I1
{
    void A();
}

interface I2: I1
{
    final void A() { }
}

class B: I2
{
   //It is an error to declare this class either with A or 
without it
}

Thanks, I think that explains it, although neither the 
documentation nor the compiler messages make things clear.
