We are not declaring Lungbarrow non-DWU just because it conflicts with later stories. I personally ignore the looms in my headcanon, but I acknowledge that Lungbarrow, while it may not be canon to the TV series, is canon to the New Adventures, and that because of this there is no such thing as a definite canon when it comes to the Whoniverse as a whole.

EDIT: Whoniverse canon is loosely defined, I doubt Moffat had Lungbarrow in mind when he wrote Listen. New Adventures writers, on the other hand, had more interest in following Lungbarrow and would at least note that it would cause continuity errors.
