It's like car airbags: let's all surround ourself with explosives...
And no, it most probably does not work with larger blades, because of the kinetic energy they have. One reason Sawstop table saws are so well made is that the bearings, trunnions, etc. have to withstand the forces involved when the protection system detonates.
When I was trying to fit a lightbulb brake to my KGS300, I did the calculations. I can't remember the detail but IIRC, the KE goes up with the square of the moment of inertia, which in turn depends on the mass and the radius of the disc (blade), and obviously the mass increases with the blade diameter too.
