To answer your question directly, no I have not. I do wonder if that is a local code where the person made the video. In my professional capacity I cannot tell you how many times I was told it was 'code' to have a specific $$$ product only to find out it was a misinterpretation of the code, or some salesman trying to press product via the inspectors. I've seem them get really pissy about sealing off boxes for air leakage here in the desert.
