While you are right and I applauded your caution. It is also fair to note that no (electronically non-conductive) heat dissipation mod is likely going to cause a runaway thermal event hot enough put the kind of stress you are talking about on a battery, at least not on an M1 Air. If you were using liquid metal and it caused a short, sure, but that is a regularly occurring issue with liquid metal. This is an electronically non-conductive thermal pad with, what do you figure, a 5w/mK thermal conductivity? On a device that probably never cracks 15w peak. And you can bet if it does, it would only sustains that output on the order of seconds. That said, I'm all for stopping unskilled people from attempting unsafe things. But then again, doing those sorts of things would sum up my hobbies neatly.
