I'd agree completely but this could just be due to logistical constraints of the ANAE, I took a course with Charles Boberg (one of the authors of the ANAE) and he was definitely aware of that, I vaguely recall learning from him that the Newfoundlander accent traditionally doesn't have t/d flapping which is totally unique in North America. Great class, he definitely has an incredible knack for precisely imitating accents.
