Not if the type is nested inside a namespace.  If your code is full of

  namespace N {
    class C {
      ...
    };
  }

then, as far as I can tell, you can't tell that C is really N::C
without either DW_TAG_namespace or demangled names.  And if you think
it's C, then users get confused if they refer to it as N::C and
nothing happens, and you get constant RTTI warnings when printing out
stuff.  (Which, besides being annoying, make ddd impossible to use,
which matters to some people.)

Namespace deduction is less important, I agree.
