I fail to understand how this is functionally different from having a
private member in the class that emits the signal and having another
class (which is declared friend of the first class) call that method.
Substantially it simply would remove an indirection level.

Uh, wait. Your example assumes that I don't have access to QDns in the
first place, right?
