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.
I do that to my neighbor all the time just so that he sees it every morning at 7am when his dumb retired ass leaves to go play golf and socialize with his stupid friends.
Jokes on you buddy! I’m over here raising three kids, working 60 hours a week, and still find time to cut my own yard!
