Interesting about the APP. I use them exclusively in my helis and airplanes. Over the past 3 years of use they have proven to be very reliable.

Here's an interesting video:

Failed at 380 amps.

Of course if yours failed due to sparking, then the Emcotec switch prevents that

I also use the Emcotec switches for my main RX packs. No physical disconnect there either, so should I be concerned about it failing and turning on? I guess I am not understanding the Cave-man approach that there must be a physical disconnection. But for now it does not matter. When, and if, the AMA changes the rule then I will worry about what to do. For now I will continue on in blissful ignorance.
