Happy end of the year....

I have no insight whether/how this can be actiated (not using a fb7530 myself), but at least this is making it out to the unwashed masses in Germany... (The FB7530 is the "value" box for the most recent DSL variant deployed in Germany, profile 35b vectoring, sold under the moniker "super-vectoring").
