Paul Vixie is deeply wrong about DoH, and the logic he uses to describe the control he demands over his local network (which he runs with apparently the same rigor that Allstate runs their corp net) isn't coherent: he's required to concede that he doesn't have control over all his machines (else he could just do what serious security teams do and manage his machines centrally, and wouldn't have control problems with DoH), but he's giving them all access to his network anyways (else DoH wouldn't matter to begin with).
Consider carefully why you think his approach is fundamentally correct. His talk opens with multiple slides talking about how improved performance is relevant only for serving advertisements. That's an alarming thing for an influential standards person to say out loud.
