Of course I'm amazed the GA world is insisting on using its own propriety standard when there are two internationally recognised ones available, so it looks like we can all play the over-simplifying someone else's problems game.
This reminds me of the discussion about securing cockpit doors before 9/11. The objection was that a locked door could cause structural issues if the cabin were decompressed during a hijacking.
Funny how quickly that got fixed subsequently....
