The difficulty many of us have with this screen is access. The FAB plate covers half of the bolt, and then it is sealed with RTV. To get it off, you have to remove the airbox, plate on the bottom of the carb or FI air handler - along with the aforementioned RTV, and then remove the screen (that's the easy part). Not saying it shouldn't be done - I've done it many times, but it's a lot of work for what is normally zero results. Easy to blow off as unnecessary after you've done it many times. I'm not saying that not doing the inspection is justified - it isn't, but that is why so many don't do it. The efficiently designed airbox many of us have that does a marvelous job of feeding our air intake system with ram air is covering up a vital inspection access point.
