As I said earlier, I've read that Chimay actually uses flour in their beers... so Treehouse, Trillium, Tired Hand etc may not use flour, but some breweries do. When you get down to the brass tacks here wheat flour is ground up wheat without the husks (and obviously not malted). With enough flaked wheat, you could probably get the same result as I got. The flour just made it easier to achieve. When using flour in the boil, that doesn't allow the starch to get converted in the mash and will create some intentional starch haze... I haven't used more than a tablespoon yet in that area.
